Description

Sanitary cleaning device

Technical Field

The present invention relates to a sanitary washing device for washing a part of a human body.

Background

In a conventional sanitary washing apparatus, a washing nozzle is projected from a storage position to a hip washing position or a female private parts washing position. The washing device is configured to discharge washing water from a discharge port of the washing nozzle to wash a part of the human body.

Specifically, for example, japanese patent application laid-open No. 2000-104319 (hereinafter referred to as "patent document 1") proposes a sanitary washing device including a spray nozzle for spraying foam to the inner surface of a toilet bowl before defecation to form a foam film on the inner surface of the toilet bowl, in addition to a washing nozzle for washing a part of a human body.

In the sanitary washing device described in patent document 1, when the detection unit detects that the user is seated, the foam is automatically sprayed from the spray nozzle. Thereby, a foam film is formed on the inner surface of the toilet bowl before defecation to prevent the adhesion of dirt to the inner surface of the toilet bowl.

However, in the sanitary washing apparatus, there may be a portion where the foam does not sufficiently spread on the inner surface of the toilet bowl. Therefore, a sufficient effect may not be expected as a measure for removing dirt from the inner surface of the toilet bowl.

Disclosure of Invention

The invention provides a sanitary washing device, which can utilize water containing washing foam to wash the inner surface of a toilet bowl from the vicinity of a rim at the upper part of the toilet bowl to the lower part with a toilet bowl drainage outlet without unevenness, thereby inhibiting dirt.

The sanitary washing device of the present invention comprises: a flushing switch; and a toilet bowl washing flow path including a flush valve that is opened and closed by a signal of a flush switch, and having a toilet bowl outlet disposed near a rim of an upper portion of the toilet bowl. Further, the sanitary washing device includes: a toilet bowl which discharges water from a toilet bowl outlet at a lower part of the toilet bowl while rotating around a rim at an upper part of the toilet bowl; a main body provided on the toilet bowl; and a foam generating part that generates a cleaning foam. The sanitary washing device further includes: a dispersion nozzle which sprays washing water or washing foam to an inner surface of the toilet bowl; a dispensing nozzle driving section that drives the dispensing nozzle; and a control section. The control unit is configured to eject the wash foam from the spray nozzle toward the inner surface of the toilet bowl or the water near the toilet bowl outlet when the flush valve is opened by an on signal of the flush switch and the water is ejected from the toilet bowl outlet to the vicinity of the rim at the upper part of the toilet bowl.

According to this configuration, the control unit opens the flush valve by the on signal of the flush switch, and causes the water for flushing the toilet to be ejected from the toilet outlet of the toilet flushing flow path. At this time, the cleaning foam is ejected from the dispersion nozzle toward the ejected water. Thus, the water mixed with the cleansing foam turns around near the rim of the upper portion of the toilet bowl and flows to the lower portion of the toilet bowl. That is, the water containing the wash foam is discharged so as to reach the inner surface of the toilet bowl over a wide range, and thus the generation of a region where the wash foam is not spread is suppressed. As a result, the inner surface of the toilet bowl can be uniformly and effectively cleaned, and the generation of dirt can be suppressed.

When the human body detecting sensor 450 of the remote controller 400 detects that a human enters the room, the bubble covering operation is performed. Specifically, before use, the spray nozzle 550 is automatically rotated to spread the foam in a large area of the inner circumference of the toilet bowl, thereby forming a foam film. Thereby preventing the adhesion of dirt to the inner surface of the toilet bowl.

When the user operates the manual splash guard switch 434 of the remote controller 400, the splash guard operation is performed. Specifically, the direction of the discharge port 550u of the spray nozzle 550 is first driven to rotate toward the toilet bowl rear. Then, a large amount of foam is rapidly spread in a direction in which the spout 550u is fixedly stopped, thereby forming a foam film on the upper portion of the water surface in the toilet bowl. Thereby preventing splash and splash of urine during urination.

The regular running of the foam is performed by a pressing operation of a user, and the foam is automatically and regularly spread in the toilet bowl during the non-use period. This retains the foam film formed on the upper part of the water surface in the toilet bowl, thereby suppressing the adhesion of dirt to the vicinity of the waterline.

The operation unit 210 is configured as described above.

In addition, as shown in fig. 14, the sanitary washing device 100 is provided with a foam tank 532, a lotion tank 533, a lotion pump 534, an air pump 535, and the like of a foam generating part 560 generating washing foam, inside the side casing 250, with the operation part 210 at the upper part of the side casing 250.

As shown in fig. 6, washing unit 500 includes at least a nozzle device 800 for discharging washing water, and a series of washing water supply passages 690 for supplying washing water from water supply connection port 510 to nozzle device 800.

A water supply connection port 510, a filter 511, a check valve 512, a constant flow valve 513, a water stop solenoid valve 514, a relief valve 515, a sub tank 600, a heat exchanger 700, a buffer tank 750, a water pump 516 constituting a water output variable portion, a flow control valve 517, and the like are provided in this order in the washing water supply flow path 690. Finally, washing water supply flow path 690 is connected to nozzle device 800.

The water supply connection port 510 is disposed on the lower right side of the main body 200 and connected to, for example, an external water supply line. The filter 511 is disposed inside the water supply connection port 510 to prevent impurities and the like contained in the tap water from flowing in. The check valve 512 prevents water stored in the subtank 600 from flowing backward into the service water line.

The constant flow valve 513 is disposed downstream of the check valve 512, and keeps the amount of the washing water flowing into the washing water supply flow path 690 constant. The water stop solenoid valve 514 electrically opens and closes the washing water supply flow path 690 in response to a signal from the control unit 130. As shown in fig. 7, the constant flow valve 513, the water stop solenoid valve 514, and the relief valve 515 are integrally formed.

The reservoir tank 600 is disposed downstream of the water stop solenoid valve 514 and includes an atmosphere opening port 603.

rings

550e and 550 f. In addition, an X-ring may be used instead of the O-ring 550 f. This can reduce the torque required for rotating the rotary nozzle 550 d. Further, the seizing of the rotary nozzle 550d can be prevented more reliably. As a result, the distribution nozzle driving unit 550a can use a small-sized and low-torque motor.

The rotary nozzle 550d is fitted to the distribution nozzle driving unit 550a via a shaft 550n and is rotationally driven.

The distribution nozzle 550 of the present embodiment is configured as described above, and operates as follows.

First, the washing water or the washing foam generated by the foam generation unit 560 shown in fig. 6 is supplied from the inlet flow path 550b of the main body 550c of the spray nozzle 550. The supplied washing water or washing foam is supplied into the rotary nozzle 550d from a plurality of inlet holes 550h opened around the rotary nozzle 550 d. Then, the supplied washing water or washing foam is discharged from the discharge port 550u of the rotary nozzle 550d toward the inner surface of the toilet bowl and the hip-washing nozzle 831.

As shown in fig. 10 and 11, the distribution nozzle 550 is disposed on the right side of the center of the main body 200. This is because the hip cleaning nozzle 831 and the like, which are cleaning nozzles for locally cleaning the human body, are preferentially arranged at the center. Therefore, the distribution nozzle 550 is disposed on either the left or right side, not the center. In addition, the above configuration may of course be reversed.

Next, the ejection control of the spray nozzle 550 will be described with reference to fig. 6.

Next, the discharge control in the rotating and foam-dispensing issuing mode of the dispensing nozzle 550 when the user is in the non-seated state and the toilet seat is in the closed state will be described.

First, when the user enters the toilet, the control unit 130 of the sanitary washing apparatus 100 detects that a person enters the room by the human body detection sensor 450. At this time, the control unit 130 is set to a rotating foam dispensing (foam covering) mode in which the cleansing foam is dispensed into the toilet bowl while rotating the discharge port 550u of the dispensing nozzle 550 in the direction of rotation. Thereby, the control part 130 shifts to an action of rotationally spreading the bubbles into the toilet stool 110. After that, the control unit 130 starts the operation of the water pump 516 shown in fig. 6. Then, control unit 130 opens opening/closing valve 530a of branch flow path 530.

In this case, the flow control valve 517 for switching the flow paths to the hip-washing nozzle 831, the private parts-washing nozzle 832, the nozzle cleaning portion 833, and the like is closed. Therefore, the washing water from the heat exchanger 700 is supplied to the distribution nozzle 550 via the branch flow path 530, the check valve 531 constituting the bubble generating unit 560, and the bubble tank 532. The supplied washing water is discharged from the discharge port 550u of the distribution nozzle 550 toward the inner surface of the toilet bowl, the hip-washing nozzle 831, and the like.

That is, the control unit 130 drives the spray nozzle driving unit 550a of the spray nozzle 550 to rotate the discharge port 550u of the rotating nozzle 550 d. At this time, the washing water or the washing foam discharged from the discharge port 550u is spread over the entire circumference of the inner surface of the toilet bowl 110 and the hip washing nozzle 831, etc., and forms a water film or a foam film. Thereby, the dirt and the like are prevented from adhering to the inner surface of the toilet bowl.

In addition, as shown in fig. 11, the distance from the discharge port 550u of the distribution nozzle 550 to the inner surface of the toilet bowl is different according to the rotation angle direction of the distribution nozzle 550.

That is, when the rotation angle of the distribution nozzle 550 disposed at the above-described position is changed, as shown in fig. 11, when the rotation angle of the discharge port 550u of the distribution nozzle 550 is 160 °, the distance from the discharge port 550u to the toilet bowl inner surface is longest (farther). On the other hand, when the rotation angle of the discharge port 550u is 340 ° (corresponding to the position rotated by 180 ° from 160 °), the distance from the discharge port 550u to the toilet bowl inner surface is shortest (close).

Therefore, the control unit 130 controls the output of the water pump 516 constituting the water discharge amount varying unit to vary according to the rotation angle (distance) of the discharge port 550u of the distribution nozzle 550 as shown in fig. 12.

Next, a method of controlling the output of the water pump 516 according to the rotation angle of the distribution nozzle 550 will be described.

First, when the human body sensor 450 detects that the user enters the toilet, the control unit 130 starts the control.

At this time, the control unit 130 changes the output of the water pump 516 from "high" to "low" as shown in fig. 12 according to the rotation angle of the discharge port 550u of the distribution nozzle 550, and discharges the cleansing foam or the like.

Specifically, the control unit 130 increases the output of the water pump 516 as shown in fig. 12 around the rotation angle 160 ° at which the distance from the inner surface of the toilet bowl is the longest (far) as shown in fig. 11. On the other hand, the control unit 130 decreases the output of the water pump 516 around a rotation angle of 340 ° at which the distance to the inner surface of the toilet bowl is shortest (close).

More specifically, the control unit 130 changes the output of the water pump 516 from "low" to "medium" stepwise or continuously in a range of the rotation angle from 0 ° to 160 °, as shown in fig. 12. Similarly, the control unit 130 changes the output of the water pump 516 from "medium" to "low" stepwise or continuously in the range of the rotation angle from 160 ° to 340 °. Thereby, the washing water or the washing foam is spread over the entire circumference of the inner surface of the toilet bowl to a predetermined height range according to the distance from the spouting port 550u to the inner surface of the toilet bowl.

Fig. 12 illustrates an operation of the distribution nozzle 550 provided with a rotation restricting unit described later as an example. Therefore, the graph is shown with the output change of the water pump 516 in the range of the rotation angle from 0 ° to 340 °. However, in the case of a configuration in which the rotation restricting portion is not provided, it is needless to say that the output of the water pump 516 may be changed in a range of one rotation of the rotation angle from 0 ° to 360 °.

That is, the control part 130 controls the discharge amount (and the discharge speed) of the washing water or wash foam from the discharge port 550u according to the rotation angle of the spray nozzle 550, that is, the distance between the discharge port 550u and the inner surface of the toilet bowl.

More specifically, when the wash foam and the wash water are discharged to the front of the toilet bowl located at the farthest distance from the discharge port 550u of the spray nozzle 550, the output of the water pump 516 is set to "medium", and the wash foam and the wash water are forcibly discharged. Thus, the washing foam and the washing water can be sufficiently spread over the inner surface of the toilet bowl in front thereof.

On the other hand, when the wash foam and the wash water are discharged to the rear of the toilet bowl located at the closest distance from the discharge port 550u of the spray nozzle 550, the output of the water pump 516 is set to "low", and the wash foam and the wash water are discharged at the weakest potential. This can prevent the occurrence of such problems as washing foam and washing water splash in advance.

And, washing water or washing bubbles are previously sprayed to the entire inner surface of the toilet bowl before use to form a water film or a bubble film. This suppresses the adhesion of dirt to the inner surface of the toilet bowl during use.

Further, in the present embodiment, in the case where the entry of the user into the toilet room is detected by the human body detecting sensor 450, or the user operates the dispersion switch 417 by means of the operating part 210 or the remote controller 400, the control part 130 performs so-called toilet foam dispersion, that is, dispersion of the washing foam to the inner surface of the toilet bowl in advance, before use.

At this time, when the toilet foam is dispensed based on the toilet foam dispensing signal, the control unit 130 dispenses the wash foam to the toilet inner surface while changing the output of the water pump 516 constituting the water discharge amount changing unit, as shown in fig. 12. Specifically, the control portion 130 first rotates the spray nozzle driving portion 550a in the normal direction (for example, clockwise) to move the direction of the discharge port 550u of the rotary nozzle 550d from the toilet bowl rear to the toilet bowl rear via the toilet bowl front, and at the same time, sprays the wash foam. Further, the control portion 130 then reverses the spray nozzle driving portion 550a (e.g., rotates counterclockwise) to move the direction of the spout 550u of the rotary nozzle 550d in a direction from the toilet bowl rear, through the toilet bowl front, and back to the toilet bowl rear, while spraying the wash foam. That is, the discharge port 550u of the rotary nozzle 550d is rotationally moved in the forward and backward directions over the inner peripheral surface of the toilet bowl, and the step operation of spreading the wash foam by at least one reciprocating rotational operation is performed.

At this time, the control part 130 controls the output of the water discharge amount varying part so that the wash foam reaches the vicinity of the rim 110a of the toilet stool 110. Thus, the wash foam is pre-dispensed to substantially the entire circumference (including the entire circumference) of the inner surface of the toilet bowl prior to use. As a result, a foam film can be formed on the front to rear inner surface of the toilet bowl, and attachment of dirt can be suppressed.

In this case, it is preferable that: as shown in fig. 12, the control unit 130 controls the discharge amount varying unit to discharge the cleansing foam at a lower output when the dispensing nozzle driving unit 550a rotates forward than when the dispensing nozzle driving unit 550a rotates backward.

If the output of the water discharge amount variable part is made low, the cleaning foam can be spread to a close place (position) from the spray nozzle because the momentum of spraying the cleaning foam is weak. Specifically, as shown by the spreading movement locus TF indicated by the broken line in fig. 11, when the toilet bowl is rotated in the normal direction (clockwise direction), the direction of the discharge port 550u of the rotary nozzle 550d is directed toward the side close to the draft surface 110b on the inner side of the rim 110a of the toilet bowl 110 to spread the wash foam.

On the other hand, if the output of the water discharge amount variable portion is made high, the momentum of the discharged cleansing foam is strong, and therefore the cleansing foam can be spread to a remote place (position) from the spreading nozzle. Specifically, as shown by a scattering movement locus TR indicated by a dotted line in fig. 11, when the rotation is reversed (counterclockwise rotation), the direction of the discharge port 550u of the rotary nozzle 550d is directed to the side close to the rim 110a of the toilet bowl 110 to scatter the wash foam.

Thus, at the beginning of the start of the spreading (at the time of normal rotation), the top surface 110b of the toilet bowl 110 at the top of the discharge port 115 can be covered with the wash foam. Then, upon reversal, the wash foam can be spread to substantially the entire circumference of the inner surface of the toilet bowl 110 near the rim 110 a. As a result, a foam film can be formed from the front to rear draft surface 110b of the toilet bowl and from the draft surface 110b to the inner surface of the rim 110a, and attachment of dirt can be effectively suppressed.

In the present embodiment, as shown in fig. 2, 9, 10, 11, and the like, the distribution nozzle 550 is disposed at a position in front of the main body 200 mounted on the toilet bowl 110. That is, the spray nozzle 550 is provided at a position on the front side from the front end position of the storage state of the nozzle device 800, wherein the nozzle device 800 protrudes from the storage position of the buttocks-washing nozzle 831 to the buttocks-washing or female private parts-washing position to perform human body washing. Thus, when the toilet is rotationally driven, the direction of the discharge port 550u of the rotary nozzle 550d can be directed rearward of the toilet 110 to dispense the wash foam. As a result, a foam film of the cleansing foam is formed on the front to rear inner surface of the toilet bowl 110, and attachment of dirt can be suppressed.

In the above description, the configuration of controlling the water pump 516 constituting the water discharge amount varying unit to vary the output when rotationally distributing the cleansing foam into the toilet bowl has been described, but the present invention is not limited thereto. For example, this may be the case: when the foam is spread by rotation, the output of the water pump 516 is not changed, but the spreading nozzle 550 is configured as described below, and a foam film is formed on the inner surface from the front to the rear of the toilet bowl to suppress the adhesion of dirt.

In this case, as shown in fig. 9 and 10, the rotation axis Ax of the distribution nozzle 550 is provided in the main body 200 so as to be inclined in the front-rear direction and the left-right direction. Specifically, the rotation axis Ax of the spray nozzle 550 is disposed in the front-rear direction such that the spray nozzle 550 is inclined toward the front of the toilet bowl 110 toward the lower side. Further, the rotation axis Ax of the spray nozzle 550 is disposed in the left-right direction such that the spray nozzle 550 is directed downward and inclined toward the hip cleaning nozzle 831 disposed in the center of the main body 200. According to the arrangement structure of the above-described rotation shaft Ax, the position of the ejection port 550u is raised in the case where the ejection port 550u of the dispensing nozzle 550 is directed toward the front of the toilet bowl 110, which is distant from the dispensing position. Therefore, as shown in the ejection port direction AcA of fig. 9, the cleansing foam is ejected in the horizontal direction. As a result, the wash foam can be spread to the vicinity of the rim 110a in front of the toilet bowl 110.

On the other hand, when the discharge port 550u of the spray nozzle 550 is directed rearward of the toilet bowl 110, which is located at a short distance from the spray position, the position of the discharge port 550u is lowered. Therefore, as shown in the ejection port direction AcB of fig. 9, the cleansing foam is ejected obliquely downward.

In addition, when the right side discharge port 550u of the toilet bowl 110, whose distance from the scattering position becomes gradually longer, is directed forward from the rear, the direction of the discharge port 550u is gradually raised from the discharge port direction AcB toward the discharge port direction AcA. As a result, the wash foam can be spread along the vicinity of the rim 110a on the right side of the toilet bowl 110. Further, when the left discharge port 550u of the toilet bowl 110, whose distance to the distribution position gradually decreases, is directed rearward from the front, the direction of the discharge port 550u gradually decreases from the discharge port direction AcA to the discharge port direction AcB.

That is, when the foam is rotationally dispensed, the dispensing nozzle driving portion 550a rotationally drives the direction of the discharge port 550u of the rotary nozzle 550d about the rotation axis Ax so as to dispense from the discharge port direction AcB toward the discharge port direction AcB via the discharge port direction AcA, for example. At this time, as described above, the distance from the spouting port 550u to the inner surface of the toilet bowl 110 varies with the rotation of the distribution nozzle 550. However, by arranging the rotation axis Ax of the distribution nozzle 550 obliquely, the cleansing foam is distributed while changing the height position of the discharge port 550u of the distribution nozzle 550 as shown in the discharge port direction AcA and the discharge port direction AcB with the rotation. Accordingly, along the scattering movement trajectory TR shown by a dotted arrow rotated leftward in fig. 11, a foam film can be formed on the inner surface of the toilet bowl 110 in the vicinity of the rim 110a from the front to the rear. As a result, the attachment of dirt can be suppressed on the entire inner surface of the toilet bowl 110 from the front to the rear.

According to the above configuration, when the foam is dispersed by rotation, the cleaning foam is discharged at a constant output without changing the output of the water pump 516. Therefore, even when the foam is dispersed in the rotation rotating to the right, the washing foam is dispersed in the opposite direction in the same trajectory as the dispersion movement trajectory TR indicated by the dotted arrow rotating to the left shown in fig. 11.

In the present embodiment, the rotation axis Ax of the spray nozzle 550 is arranged such that the inclination angle β in the front-rear direction shown in fig. 9 is, for example, 20 degrees, and the inclination angle γ in the left-right direction shown in fig. 10 is, for example, 10 degrees. The angle can be arbitrarily changed depending on the shape of the toilet bowl and the position where the dispensing nozzle 550 is disposed.

The height position of the discharge port 550u of the distribution nozzle 550 is set to be lower than the upper end surface 110c of the toilet bowl 110 regardless of the rotational position.

In the above description, the example in which the normal rotation is indicated as the rightward (clockwise) rotation as viewed from above in fig. 11 and the reverse rotation is indicated as the leftward (counterclockwise) rotation has been described, but the present invention is not limited thereto. For example, this may be the case: the forward rotation is a leftward rotation, and the reverse rotation is a rightward rotation. That is, the direction in which the discharge port 550u of the spray nozzle starts rotating at the time of spraying is referred to as forward rotation, and the direction in which the discharge port returns is referred to as reverse rotation.

As described above, the control unit 130 changes the output of the water pump 516 according to the rotation angle of the discharge port 550u of the distribution nozzle 550. This enables the wash water or wash foam to be discharged from the spray nozzle 550 so as to reliably reach the front, side, and rear of the inner surface of the toilet bowl 110 at different distances. As a result, a water film or a foam film can be formed over a wide area of the inner surface of the toilet bowl 110 to suppress adhesion of dirt.

In the above embodiment, the configuration in which "high" and "low" are set with reference to the average level "middle" of the output of the water pump 516 has been described as an example, but the present invention is not limited to this. For example, the following configuration may be adopted: the average level of the output of the water pump 516 may itself be increased or decreased to alter the base level. In this case, it is preferable that a level switch for adjusting the average level is provided in the operation unit 210 or the remote controller 400. Thus, even when the toilet bowl 110 in which the sanitary washing apparatus 100 is installed is different in size or the like, the washing water or the washing foam can be discharged so as to reach the entire circumference of the inner surface of the toilet bowl. Further, the height position (with respect to the horizontal plane) of the cleansing foam sprayed to the inner surface of the toilet bowl 110 may be arbitrarily changed. Thereby, a water film or a foam film can be formed at any position of the inner surface of the toilet bowl 110 to suppress adhesion of dirt.

In the above embodiment, the ejection control in which the controller 130 changes the output of the water pump 516 in accordance with the rotation angle of the ejection port 550u of the distribution nozzle 550 has been described as an example, but the present invention is not limited to this. For example, this may be the case: in addition to the change in the output of the water pump 516, the control unit 130 controls the rotation speed of the distribution nozzle driving unit 550a to be changed according to the rotation angle of the discharge port 550 u.

That is, in the present embodiment, the output of the water pump 516 is changed so as to change the discharge momentum of the washing water or the washing foam. Thereby, wash water or wash foam is reliably spread to the inner surface of the toilet stool 110 farther away, and splashing at the inner surface of the toilet stool 110 closer is effectively suppressed.

However, when the discharge port 550u of the spray nozzle 550 is rotated at a constant rotation speed, the spray density of the wash foam and the wash water becomes sparse at a distance from the toilet bowl inner surface. On the other hand, the distribution density of the wash foam and wash water becomes dense at a position close to the inner surface of the toilet bowl.

Therefore, in the present embodiment, the rotation speed of the distribution nozzle 550 may be changed by the distribution nozzle driving portion 550a according to the rotation angle of the discharge port 550 u. This allows the washing water or the washing foam to be uniformly distributed over the entire circumference of the inner surface of the toilet bowl 110.

In addition, even when the output of the water pump 516 is changed to distribute the wash foam and the wash water, the distribution density of the wash foam and the wash water can be equalized to some extent.

However, when the rotational speed of the distribution nozzle driving part 550a is changed according to the rotational speed of the distribution nozzle 550 to distribute the washing foam and the washing water, the distribution density can be more equalized. In other words, the wash foam and the wash water can be spread over the entire circumference of the inner surface of the toilet bowl 110 with a more uniform distribution density.

That is, when the rotation speed is fixed, as shown in fig. 11, the wash water or wash foam spread to the vicinity of the rotation angle of 160 ° at which the distance from the discharge port 550u of the scattering nozzle 550 is the farthest, that is, in front of the toilet bowl 110 is scattered, and the distribution density becomes sparse. Therefore, when the wash foam and the wash water are discharged to the front of the toilet bowl 110, the rotation speed of the spray nozzle 550 is the slowest. Thereby, the time for the outlet 550u of the scattering nozzle 550 to pass through the vicinity of the front of the toilet bowl 110 is lengthened. As a result, the distribution density of the cleansing foam can be increased.

On the other hand, when the rotation speed is fixed, the wash foam or wash water discharged to the vicinity of a rotation angle of 340 ° at which the discharge port 550u of the discrete cloth nozzle 550 is closest, that is, to the rear of the toilet bowl 110 is concentrated, and the distribution density becomes dense. Therefore, the rotational speed of the scattering nozzle 550 is fastest. Thereby, the time for the discharge port 550u of the spray nozzle 550 to pass through the vicinity of the toilet bowl rear is shortened. As a result, the distribution density of the cleansing foam can be reduced.

That is, the distribution of the wash water or wash foam spread to the inner surface of the toilet bowl can be equalized (density is eliminated) by varying the rotation speed. Therefore, by forming a uniform foam film, adhesion of dirt can be more effectively suppressed over the entire circumference of the inner surface of the toilet bowl.

As described above, the control unit 130 changes the rotation speed of the spray nozzle driving unit 550a according to the rotation angle of the discharge port 550u of the spray nozzle 550. For example, in the case where the direction of the spouting port 550u of the scattering nozzle 550 is directed toward the rotation angle of the toilet bowl front where the distance to the toilet bowl inner surface is long, the rotation speed of the scattering nozzle driving part 550a is gradually reduced (decelerated). On the other hand, in the case where the direction of the ejection opening 550u is directed toward the rotation angle of the toilet bowl rear where the distance to the toilet bowl inner surface is short, the speed of the scattering nozzle driving part is gradually increased (increased). Thus, the washing water or the washing foam can be discharged uniformly to the front, the side and the rear of the toilet bowl with different distances without uneven distribution density. As a result, the adhesion of dirt can be effectively suppressed by the water film or the foam film uniformly formed on the inner surface of the toilet bowl.

In the present embodiment, when the human body detection sensor 450 detects that a human enters the room, the control unit 130 performs control such that: so-called toilet foam spreading, in which wash water or wash foam is previously spread from the spreading nozzle 550 to the inner surface of the toilet, is performed. Specifically, the control unit 130 performs such control as: the rotary nozzle 550d is driven to rotate, for example, at least one reciprocation by the dispensing nozzle driving part 550a and simultaneously dispenses the foam, and then is automatically stopped. Thus, a water film or a foam film is formed on the inner surface of the toilet bowl in advance before the user uses the sanitary washing apparatus. As a result, the adhesion of dirt to the inner surface of the toilet bowl during use can be effectively suppressed.

In addition, in the above, an example in which the spray nozzle 550 is rotated one reciprocation to spray the washing foam and the washing water before use is explained, but is not limited thereto. For example, the number of times is arbitrary as long as the number of times the scattered wash foam and wash water can sufficiently reach the inner surface of the toilet bowl. In this case, it is preferable that the user can select and set the number of reciprocations of the toilet foam dispensing through the operation part 210 or the remote controller 400.

In the above embodiment, the rotation direction of the distribution nozzle 550 is not particularly mentioned, but as shown in fig. 12, the rotary nozzle 550d is rotated one round. This is because, in the case of the structure in which the rotary nozzle 550d of the spray nozzle 550 is rotated only in any one of the right and left directions through the entire circumference, the spray direction of the washing water or the washing foam is always the same direction. Therefore, in the present embodiment, the wash foam and the wash water are distributed to the inner surface of the toilet bowl from both the forward and reverse rotation directions by one reciprocating rotation. This can further reduce the occurrence of a so-called scatter leakage. Therefore, the washing foam and the washing water can be more uniformly spread to the inner surface of the toilet bowl. As a result, the adhesion of the dirt to the inner surface of the toilet bowl can be suppressed with a small number of times (time) of spreading. The reciprocating rotation is not limited to one reciprocation, and may be set to two reciprocations or three reciprocations or the like.

Specifically, as shown in fig. 12, the rotary nozzle 550d of the distribution nozzle 550 is first rotated in the forward direction from 0 ° corresponding to the rotation angle on the rear side of the toilet bowl 110 (for example, rotated in the clockwise direction) to 340 ° and temporarily stopped. Then, the rotary nozzle 550d is reversed (e.g., rotated counterclockwise) from the rotation angle of 340 ° to the rotation angle of 0 °, and is stopped after one reciprocating rotation.

In this case, it is preferable to provide a rotation restricting portion (not shown) as a mechanical stopper, for example, which restricts the rotatable range of the rotating nozzle 550d of the distribution nozzle 550 to a rotation angle of 0 ° to a rotation angle of 340 °.

Specifically, the rotation restricting portion is constituted by, for example, a protrusion formed on a part of the outer periphery of the rotary nozzle 550d and a rotation restricting wall of the main body 550 c. According to this configuration, when the projection rotates to physically abut against the rotation restricting wall, the operation of the rotary nozzle 550d to be rotated is restricted. That is, the motor constituting the spray nozzle driving unit 550a slides and idles by contact. Thereby, the rotation nozzle 550d is restricted from rotating beyond the rotatable range.

As described above, the distribution nozzle 550 of the above configuration is provided with the rotation restricting portion that restricts the rotation range, and the distribution nozzle 550 is reciprocally rotated within the rotation range that is not restricted by the rotation restricting portion. And, the wash foam and the wash water are spread to the inner surface of the toilet bowl from both directions of forward and reverse rotation based on the reciprocating rotation. This reduces the occurrence of a so-called scatter leakage. Thus, the wash foam and the wash water can be more uniformly spread to the inner surface of the toilet bowl. As a result, a foam film capable of suppressing adhesion of dirt to the inner surface of the toilet bowl can be formed with a small number of times (time) of spreading.

The control unit 130 always recognizes the position where the projection of the rotary nozzle 550d of the distribution nozzle 550 configured as described above abuts the rotation restricting portion as the origin of the rotational position of the distribution nozzle driving unit 550 a. Therefore, the origin can be prevented from being displaced by the reciprocating operation of the rotary nozzle 550 d. This can improve the positional accuracy of the swivel nozzle 550d with respect to the swivel angle of the toilet bowl inner surface. In other words, variations such as positional shifts can be reduced with respect to a predetermined position of the toilet bowl inner surface. As a result, the cleansing foam and the cleansing water can be distributed to the accurate position of the inner surface of the toilet bowl from the discharge port 550u of the distribution nozzle 550 at an appropriate discharge output and rotation speed.

In the above description, the configuration in which the rotation range of the distribution nozzle 550 is physically limited is described as an example, but the present invention is not limited thereto. When the positional deviation of the origin of the spray nozzle 550 is not a problem, the forward and reverse rotation operations of the spray nozzle 550 may be performed only by the spray nozzle driving unit 550 a. This makes it possible to perform various operations of the rotary nozzle 550d, such as forward and reverse rotation and unidirectional rotation, without requiring a rotation restricting section. As a result, the rotary nozzle 550d can be operated more appropriately according to the state of dirt or the like on the inner surface of the toilet bowl. In this case, it is preferable to control the origin of the distribution nozzle 550 to be set in the vicinity of the reversed rotation angle of 160 °, and the rotation speed is gradually reduced in the vicinity. This reduces the load applied when the spray nozzle driving unit 550a is suddenly reversed.

Next, the structure of the bubble generating unit 560 of the sanitary washing device according to the present embodiment will be described with reference to fig. 6.

As shown in fig. 6, the bubble generating unit 560 is connected to a branch flow path 530 via an opening/closing valve 530a and a check valve 531, and the branch flow path 530 branches off from a wash water supply flow path 690 between the water pump 516 and the flow control valve 517 constituting the water output amount varying unit. Further, by opening and closing valve 530a, washing water is supplied to bubble generation unit 560 through branch flow path 530.

A dispensing nozzle 550 is connected downstream of the foam box 532. The bubble tank 532 is connected to a lotion tank 533 which supplies lotion via a lotion pump 534.

The foam box 532 is also connected to an air pump 535. The air pump 535 sends air into the foam tank 532 and generates cleaning foam and the like. Further, the air pump 535 supplies the cleaning water and the generated cleaning bubbles to the spray nozzle 550.

The bubble generating unit 560 is configured as described above and operates as follows.

First, the control unit 130 opens the opening/closing valve 530 a. Then, the control part 130 drives the water pump 516 to transfer the washing water from the heat exchanger 700 to the bubble tank 532 of the bubble generating part 560. At this time, the wash supplied from the wash tank 533 by the wash pump 534 is mixed with the washing water supplied from the heat exchanger 700 in the bubble tank 532.

Then, the control part 130 drives the air pump 535 to supply air into the bubble tank 532. Thereby, the cleaning foam is generated in the foam tank 532. The generated wash foam is supplied to the spray nozzle 550 and is ejected from the ejection port 550u of the rotary nozzle 550d to the inner surface of the toilet bowl.

At this time, the ejection amount and the ejection momentum (ejection speed and ejection pressure) of the cleaning water or the cleaning bubbles ejected from the spray nozzle 550 are increased or decreased according to the increase or decrease in the outputs of the water pump 516 and the air pump 535. Thus, as described with reference to fig. 11, the wash foam and the wash water can be uniformly distributed to the inner surface of the toilet bowl. That is, the air pump 535 of the foam generating unit 560 also functions as a water discharge amount varying unit in the same manner as the water pump 516.

In the above description, the configuration in which the opening/closing valve 530a is provided in the branch flow path 530 has been described as an example, but the present invention is not limited thereto. For example, the following structure is also possible: a flow path switching valve is provided at a branching portion between the branching flow path 530 and the wash water supply flow path 690.

That is, the foam generating unit 560 of the present embodiment includes the foam tank 532 between the on-off valve 530a and the spray nozzle 550. The bubble tank 532 is supplied with the lotion from the lotion tank 533 to generate the cleansing bubbles. Has the following structure: the generated wash foam is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl.

Thus, a foam film of the cleansing foam containing the lotion is formed on the inner surface of the toilet bowl, not just a simple water film generated by water or hot water dispersion. As a result, adhesion of dirt to the inner surface of the toilet bowl can be more effectively suppressed.

Further, odor caused by dirt and the like can be effectively suppressed by the cleaning foam containing the detergent. Also, the cleansing foam gives the user a visually clean impression. As a result, the comfort of the user is further improved.

In addition, in the above-described embodiment, the configuration in which the distribution of the washing water or the washing foam to the inner surface of the toilet bowl is performed in the case where the human body detection sensor 450 detects that a human body enters the room is exemplified, but not limited thereto. For example, the distribution may be performed by a person operating the distribution switch 417 provided in the operation unit 210 or the remote controller 400. Thus, even when a toilet bowl as a sanitary washing apparatus is not used, when there is concern about the dirt on the inner surface of the toilet bowl, it is possible to remove the dirt by spreading washing foam containing a detergent on the inner surface of the toilet bowl. Further, it is possible to prevent the formation of tough dirt on the draft surface 110b and the like due to drying. That is, by the user operating the distribution switch 417, a foam film formed of the wash foam containing the detergent can be formed on the inner surface of the toilet bowl at any time. As a result, the inner surface of the toilet bowl can be kept clean.

In the above embodiment, the following configuration may be provided: the user arbitrarily selects which of the wash water and the wash foam is to be sprayed to the inner surface of the toilet bowl in advance by using the operation unit 210 or a spray selection switch (not shown) of the remote controller 400. Thus, the necessity of spreading the dirt or odor on the inner surface of the toilet can be arbitrarily selected according to the occurrence of the dirt or odor. As a result, wasteful use of the lotion can be suppressed, and cost performance can be improved.

In the above embodiment, the control unit 130 may have a wash/issue mode in which an instruction can be selected by the operation unit 210 or a switch button of the remote controller 400.

In this case, in the wash and rinse mode, the control unit 130 first opens the on-off valve 530a while stopping the lotion pump 534 (supplying the lotion from the lotion tank 533 of the foam generation unit 560 to the foam tank 532). Thereby, the water pump 516 sends the washing water to the bubble tank 532. The transferred washing water is supplied from the bubble tank 532 to the spray nozzle 550 and is discharged into the toilet stool 110.

At this time, a path from the bubble tank 532 to the spray nozzle 550 is first washed with washing water. Thus, if the detergent remains in the passage or the spray nozzle 550, the detergent is washed away with the washing water. Therefore, clogging of the path or the distribution nozzle 550 and poor rotation of the distribution nozzle 550 due to adhesion of the lotion can be prevented. Further, the inner surface of the toilet bowl can be washed with the washing water in advance.

That is, during the brushing operation in the brushing and styling mode, the lotion pump 534 is stopped. Therefore, the lotion is not supplied to the bubble tank 532, but only the washing water is transferred. Thereby, the path from the bubble tank 532 to the spray nozzle 550 is washed by the supplied washing water. Meanwhile, the wash water after washing the path is distributed from the distribution nozzle 550 to the inner surface of the toilet bowl. As a result, the inner surface of the toilet bowl is also cleaned with the washing water together with the cleaning of the path.

In the washing operation in the washing and brushing mode, washing is generally performed with washing water that is not subjected to temperature control. However, the washing operation may be performed by heating the washing water to, for example, about 40 ℃ by the heat exchanger 700 and supplying the heated washing water. This improves the solubility of the remaining detergent or the like in the washing water, thereby obtaining a more excellent washing effect.

In the above-described washing and brushing mode, the path and the inner surface of the toilet bowl may be washed as desired by the user operating the washing switch 223 of the operation unit 210.

Specifically, as shown in fig. 4, a wash lamp 223a such as an LED is provided near the wash switch 223 of the operation unit 210 that is in the wash and issue mode. When a predetermined time, for example, 20 days, has elapsed after the previous brushing is performed, the control unit 130 automatically blinks the brush lamp 223 a. This prevents the occurrence of clogging of the route or the like by preventing forgetting to wash.

Alternatively, this may be the case: when the cleansing foam is sprayed to the toilet bowl inner surface, the control unit 130 changes the output of the air pump 535 in accordance with the rotation angle of the discharge port 550u of the spray nozzle 550, in the same manner as the output operation of the water pump 516 shown in fig. 12, and sprays the cleansing foam from the discharge port 550 u. Thus, the cleansing foam can be discharged to the front, the side, and the rear of the toilet bowl at different distances so as to be effectively spread over the cleansing foam. As a result, a foam film can be formed on the entire inner surface of the toilet bowl to suppress adhesion of dirt.

Specifically, as described with reference to fig. 11, the control unit 130 increases (increases) the output (air pressure) of the air pump 535 at a rotation angle of about 160 ° at which the distance from the discharge port 550u of the spray nozzle 550 to the toilet bowl inner surface is longest (farther). This can increase the air pressure generated by the air pump 535 to increase the force of spraying the cleaning foam from the spray opening 550u to a remote place.

On the other hand, the output (air pressure) of the air pump 535 is made small (low) in the vicinity of the rotation angle 340 ° at which the distance from the ejection port 550u to the toilet bowl inner surface is shortest (close). This reduces the air pressure of the air pump 535 to reduce the momentum of the ejection of the cleaning foam.

That is, the air pressure discharged from the air pump 535 is adjusted according to the distance from the ejection port 550u of the scattering nozzle 550 to the inner surface of the toilet bowl. As a result, the washing foam can be uniformly and uniformly discharged to the inner surface of the toilet bowl.

In the above embodiment, the following configuration may be adopted: the toilet further includes a dirt detection unit (not shown) for detecting dirt in the toilet bowl by using an image pickup Device such as a CCD (Charge Coupled Device). At this time, the control unit 130 drives the spray nozzle 550 to reciprocate a portion where dirt remains based on the detection result of the dirt detection unit, thereby intensively spraying the cleaning foam. Thus, dirt adhering to the inner surface of the toilet bowl can be effectively removed. In addition, in addition to the method of reciprocating only in the fouling portion, the following may be possible: the rotation speed of discharge port 550u of spray nozzle 550 passing through the dirt portion is rotationally driven at a lower speed. Further, the following structure is also possible: when passing through the dirty portion, the outputs of the water pump 516 and the air pump 535 are further increased. This can provide the same effect.

<4> discharge control and action and operation of a distribution nozzle when a toilet seat is opened and not seated

Next, the ejection control of the spray nozzle when the user operates the spray switch 417 in a state where the user is not seated on the toilet seat 300 and the toilet seat 300 is opened substantially vertically as in the case of male urination will be described with reference to fig. 13A and 13B.

In this case, the toilet seat 300 is in an open state because the user is in a standing posture. That is, the toilet seat opening/closing detector 331 detects the open state of the toilet seat, and the seating detector 330 detects the non-seating state.

In addition, in the <3> item, the description has been made of the rotating distribution foam for distributing the wash foam into the toilet bowl while rotating the direction of the discharge port 550u of the distribution nozzle 550 based on the rotating distribution foam firing (foam covering) mode of the control portion 130.

In the item <4>, a fixed foam will be described which is a foam for spraying the cleansing foam into the toilet bowl while keeping the direction of the discharge port 550u of the spray nozzle 550 fixed, based on the fixed foam spray (splash suppression) mode of the control unit 130.

That is, the fixed distribution foam in a state where the user is not seated on the toilet seat 300 as in the case of urination by a man and in a state where the toilet seat 300 is opened substantially vertically will be described.

Specifically, with reference to fig. 13A and 13B, the ejection control of the dispensing nozzle in the fixed dispensing foam emission mode in the case where the user operates the manual splash guard switch 434 as the dispensing switch will be described.

Fig. 13A is an explanatory diagram showing the water pump output at the time of the discharge operation of the spray nozzle to the toilet bowl inner surface. Fig. 13B is an explanatory view showing a discharge direction of the scattering nozzle to the inner surface of the toilet bowl.

In the above state, the user presses the manual splash prevention switch 434 of the operation unit 210 or the remote controller 400. The manual splash suppression switch 434 of the operation unit 210 is not particularly shown.

Thereby, the control portion 130 first drives the dispensing nozzle driving portion 550a, and rotates the direction of the discharge port 550u of the dispensing nozzle 550 to a position facing the toilet bowl rear side as shown in fig. 13B. Then, the driving of the dispensing nozzle driving portion 550a is stopped. In the case of the present embodiment, as shown in fig. 13A, the rotation angle of the ejection port 550u is stopped at a position near 20 °, for example. Thereby, the direction of the outlet 550u is directed to the rear side of the toilet bowl inner surface.

Next, as shown in fig. 13A, the control unit 130 controls the discharge output of the water pump 516 or the air pump 535 constituting the water discharge amount varying unit to a high output. Then, the washing water or the washing foam is discharged to the rear of the toilet bowl 110 for a predetermined time from the spray nozzle 550 in the direction indicated by the arrow in fig. 13B. In the present embodiment, the predetermined time is set to 8 seconds, for example.

At this time, the discharge port 550u of the spray nozzle 550 is stopped in a direction of an angle α rearward and downward with respect to the rotation axis Ax of the spray nozzle 550 shown in fig. 9. Therefore, the cleansing foam or the like is discharged from the discharge port 550u of the distribution nozzle 550 in a state of being stopped in the direction indicated by the discharge port direction AcB in fig. 9.

That is, after the direction of driving the discharge port 550u of the spray nozzle 550 is rotated toward the toilet bowl rear, the control unit 130 controls the water pump 516 to output "high" and discharges the wash foam or the like. Thus, the water surface above the discharge port 115 in the toilet bowl and the upper part of the waterline in the toilet bowl are quickly covered with wash foam or the like flowing downward from the rear. As a result, the spread of odor caused by excretion of urine or the like and the adhesion of dirt near the draft surface 110b of the toilet bowl 110 can be suppressed by the cleansing foam.

In addition, when the discharged urine falls to the vicinity of the water surface in the toilet stool 110, the wash foam covering the water surface plays a role of buffering. This can suppress the splash to the outside of the toilet 110. That is, a large amount of wash foam or the like is earlier spread in a direction in which the spray nozzle 550 is fixed, thereby forming a foam film on the upper portion of the water surface in the toilet stool 110. This prevents urine from scattering out of the toilet bowl 110 due to splashing or the like.

In the present embodiment, when the fixed foam dispensing starting mode (splash suppression mode) is set by the user operating the manual splash suppression switch 434, the rotational driving of the dispensing nozzle driving portion 550a is stopped at a position where the discharge port 550u faces the toilet bowl rear side. The following description is given by taking as an example a configuration in which the post-stop control unit 130 controls the discharge amount varying unit 516 to "high" and discharges the wash foam toward the rear of the toilet bowl, but the present invention is not limited thereto. For example, the position of the spray nozzle 550 fixing the spray of the cleansing foam may be any one of the front side, the center, the rear side, and the left and right of the toilet in the vicinity of the discharge port 115 of the toilet 110. That is, the cleaning foam may be discharged, and the water surface 110b and the upper part of the water line of the toilet bowl 110 may be quickly covered with the foam film in a short time of several seconds, for example. This can suppress splash and scattering of urine. Further, the adhesion of dirt to the vicinity of the waterline and the upper portion thereof in the toilet bowl 110 can be more reliably suppressed.

In addition, in the present embodiment, the following configuration is explained as an example: in the fixed foam dispensing commanding mode, the control portion 130 discharges the wash foam or the like from the water discharge amount varying portion 516 toward the toilet bowl rear side at a "high" output as shown in fig. 13A, but is not limited thereto. For example, the output of the water discharge amount changing unit 516 may be discharged as a "medium" output.

As described above, the sanitary washing apparatus according to the present embodiment includes: a main body 200 provided in the toilet bowl 110, a hip washing nozzle 831 for washing a human body, a bubble generating part 560 for generating washing bubbles, a spray nozzle 550 for spraying washing water or washing bubbles to an inner surface of the toilet bowl, and a discharge amount varying part 516 for varying a flow rate of the washing water to be supplied to the spray nozzle. Further, the sanitary washing device includes: a spray nozzle driving part 550a for driving the discharge port 550u of the spray nozzle, an on-off valve 530a for opening and closing a water passage to the spray nozzle, a control part 130, and an operation part 210 for setting instructions to the control part. The control unit 130 is provided with control operations of a rotating foam dispensing mode in which the cleansing foam is dispensed into the toilet bowl while rotating the discharge port 550u of the dispensing nozzle in the direction of rotation, and a fixed foam dispensing mode; in the fixed spray foam commanding mode, the wash foam is sprayed into the toilet bowl while keeping the direction of the discharge port 550u of the spray nozzle fixed.

According to this configuration, when the toilet bowl foam is dispensed in the rotating dispensing foam commanding mode, the control portion 130 dispenses the cleaning foam from the dispensing nozzle 550 into the toilet bowl in a widely distributed manner while rotating the direction of the discharge port 550u of the dispensing nozzle. Thus, the foam film is formed by the wash foam on the inner surface from the front to the rear of the toilet, and the adhesion of dirt on the inner surface of the toilet and near the waterline can be suppressed.

On the other hand, when the toilet foam dispensing in the fixed dispensing foam commanding mode is performed, the control portion 130 dispenses the wash foam into the toilet while keeping the direction of the discharge port 550u of the dispensing nozzle fixed. And then a bubble film of the washing bubble is rapidly formed on the upper portion of the water surface in the toilet stool. Thus, the water surface at the upper part of the discharge port in the toilet bowl can be quickly covered by the foam film of the cleaning foam. As a result, the cushioning effect of the cleansing foam can suppress the spread of odor during urination and the scattering of urine from the water surface when a man urinates.

Here, the effect of suppressing scattering of urine by the cleansing foam will be described with reference to the test results shown in fig. 25.

Fig. 25 is a graph showing the result of examination of the splash-suppressing effect of foam spreading in the fixed spread foam issue mode of the sanitary washing device. In fig. 25, the vertical axis represents the height (thickness) of the cleansing foam covering the draft, and the horizontal axis represents the elapsed time.

As can be seen from the results shown in fig. 25, first, the foam height of the cleansing foam decreases with the passage of time. It is also found that, at the initial stage of dispersion, if the foam height is about 5mm or more, scattering can be suppressed as compared with the case without foam.

Further, the following can be confirmed: when the foam height is about 10mm or more at the initial stage of spreading, the effect of suppressing scattering of urine or the like from the spherical surface of the toilet bowl 110 to the outside becomes remarkable. In this case, it is understood that the suppression effect decreases with the passage of time.

The following is also known: if the height of the foam is about 18mm or more, scattering of urine or the like from the spherical surface of the toilet bowl 110 to the outside can be more reliably suppressed from the initial stage of distribution to about 2 hours.

According to the above test results, it is preferable that: the lower limit of the height of the foam on the water surface in the toilet bowl generated by the foam spreading is 5mm or more, and the upper limit is 50mm or less. In particular, a range of 10mm to 50mm or less is more preferable. The upper limit of 50mm is set to a value determined by the height of foam that is not accumulated in the hip part when the user sits on the toilet seat in the sanitary washing apparatus used in the test. Therefore, in different sanitary washing apparatuses, the setting of the upper limit can be changed depending on the size and shape of the toilet bowl, the toilet seat, and the like, of course.

In the sanitary washing device according to the present embodiment, the rotation axis Ax of the discharge port 550u of the rotating nozzle 550d of the rotationally driven distribution nozzle 550 is provided in the main body 200 so as to be inclined in the front-rear direction and the left-right direction. The lower side of the distribution nozzle 550 is inclined toward the front side of the toilet 110 with respect to the rotation axis Ax with respect to the front-rear direction inclination, and the lower side of the distribution nozzle 550 is inclined toward the hip cleaning nozzle 831 with respect to the rotation axis Ax with respect to the left-right direction inclination.

According to this structure, when the toilet foam for spreading the wash foam to the toilet 110 is spread, the direction of the discharge port 550u is raised in the case of directing the discharge port 550u of the spreading nozzle 550 to the spreading position in front of the toilet where the distance becomes longer. On the other hand, when the discharge port 550u of the discharge nozzle is directed to the discharge position at the toilet bowl rear side where the distance is reduced, the direction of the discharge port 550u is lowered. Thereby, the washing foam can be spread with varying height of the discharge port 550u of the spreading nozzle according to the distance from the discharge port 550u of the spreading nozzle to the inner surface of the toilet bowl. Therefore, the wash foam can be spread on the inner surface from the front to the rear of the toilet bowl without changing the output of the water pump 516, thereby forming a foam film. As a result, adhesion of dirt to the inner surface of the toilet bowl can be suppressed.

In the sanitary washing apparatus according to the present embodiment, when the foam is spread by rotating the spray nozzle 550 toward the toilet bowl 110, the control unit 130 rotates the spray nozzle driving unit 550a in the normal direction so that the direction of the discharge port 550u rotates from the toilet bowl rear to the toilet bowl rear via the toilet bowl front. Then, the control portion 130 reverses the dispensing nozzle driving portion 550a to rotate the direction of the discharge port 550u from the toilet bowl rear through the toilet bowl front and back to the toilet bowl rear. That is, the control unit 130 controls to: the step of rotating the dispensed foam by at least one reciprocating rotational motion is performed.

According to this structure, the control portion 130 first rotates the dispensing nozzle driving portion 550a forward to move the direction of the discharge port 550u of the dispensing nozzle from the toilet bowl rear to the toilet bowl rear via the toilet bowl front, and at the same time, dispenses the wash foam. Then, the control portion 130 reverses the dispensing nozzle driving portion 550a to move the direction of the spout 550u in a direction from the toilet bowl rear through the toilet bowl front and back to the toilet bowl rear while dispensing the wash foam. That is, the cleansing foam is spread by at least one reciprocating rotational drive along the inner circumferential surface of the toilet bowl while rotationally moving the direction of the discharge port 550u of the spray nozzle 550 in the forward and reverse directions. At this time, the output of the water discharge amount variable portion 516 is controlled in such a manner as to reach the vicinity of the rim of the toilet bowl 110, so that the wash foam is spread over substantially the entire circumference of the inner surface of the toilet bowl. Thereby, a foam film can be formed on the inner surface from the front to the rear of the toilet bowl to suppress the adhesion of dirt.

The sanitary washing apparatus according to the present embodiment further includes a human body detection sensor 450 for detecting the entry and exit of a user into and from the toilet. When the human body detecting sensor 450 detects that the user enters the toilet, the control part 130 rotates to distribute the bubbles toward the inner surface of the toilet stool through at least one reciprocating rotational motion.

According to this configuration, in the case where the human body detecting sensor 450 detects that the user enters the toilet, the direction of the discharge port 550u of the dispensing nozzle is driven to perform at least one reciprocating rotation, so that the rotating dispensing foam for dispensing the washing foam to the inner surface of the toilet bowl is performed. Thus, a foam film is formed on the inner surface of the toilet bowl before use, and attachment of dirt can be suppressed.

Further, the sanitary washing device of the present embodiment includes: a bubble tank 532 to which the washing water is supplied through the water discharge amount varying unit 516 by opening the open/close valve 530a by the control unit 130; a lotion pump 534 supplying the lotion of the lotion tank 533 to the bubble tank 532; and an air pump 535 that supplies air to the foam tank. The control unit 130 controls the spray nozzle 550 to discharge the washing water or the washing foam in the foam tank 532.

According to this structure, it is possible to discharge wash foam containing a detergent to the surface of the buttocks washing nozzle 831 or the inner surface of the toilet bowl, not just water or hot water. This can improve the cleaning effect and the effect of inhibiting the adhesion of dirt. Further, the cleaning foam containing the detergent can suppress the spread of odor and the like. As a result, the user can be given a visually clean feeling and a comfortable feeling in use.

The control unit 130 of the sanitary washing apparatus according to the present embodiment has a wash and issue mode. In the wash and rinse mode, the control unit 130 opens the on-off valve 530a to deliver the washing water to the bubble tank 532 by the discharge amount varying unit 516 and discharges the washing water from the spray nozzle 550 while stopping the washing pump 534 (supplying the washing agent in the washing agent tank 533 of the bubble generating unit 560 to the bubble tank 532).

According to this structure, the path from the bubble tank 532 to the spray nozzle 550 is washed with the washing water. Thereby, clogging of the path or the distribution nozzle 550 due to adhesion of the lotion and poor rotation of the distribution nozzle 550 due to adhesion of the lotion can be prevented. In addition, the inner surface of the toilet bowl can be washed with the washing water.

In the present embodiment, the description has been given by taking as an example a configuration in which a motor is used as the distribution nozzle driving unit 550a, but the present invention is not limited thereto. The structure may be such that: the distribution nozzle 550 is rotated by a reaction when the cleansing foam is discharged from the discharge port 550u of the distribution nozzle 550. This simplifies the structure and suppresses power consumption.

In the present embodiment, the description has been given taking the configuration of the single spray nozzle 550 as an example, but the present invention is not limited thereto. For example, the following structure is also possible: such as a spreading nozzle for spreading washing foam to the vicinity of the rim 110a of the toilet stool 110; a plurality of the spray nozzles are provided, such as a spray nozzle for spraying wash foam to the vicinity of the discharge port 115 of the toilet bowl 110. In this case, the plurality of distribution nozzles may be rotated independently or may be rotated in conjunction with each other. Thereby, the wash foam can be spread to the inner surface of the toilet bowl in a short time.

In the present embodiment, the configuration in which the spray nozzle 550 includes one discharge port 550u is described as an example, but the present invention is not limited thereto. This may be the case, for example: the spray nozzle 550 is provided with a plurality of outlets such as a discharge outlet for spraying the wash foam to the vicinity of the rim 110a of the toilet bowl 110 and a discharge outlet for spraying the wash foam to the vicinity of the discharge outlet 115 of the toilet bowl 110. Thereby, the wash foam can be spread to the inner surface of the toilet bowl in a short time.

In the present embodiment, the structure in which the discharge nozzle 550 discharges the wash foam to both the vicinity of the rim 110a of the toilet bowl 110 and the vicinity of the discharge port 115 of the toilet bowl 110 has been described as an example, but the invention is not limited thereto. For example, in addition to the above, the following configuration is also possible: the wash foam is spread by the spreading nozzle 550 toward the middle position (height) of the rim 110a of the toilet bowl 110 and the discharge port 115, etc. This can further reduce the occurrence of the scattering omission portion.

As shown in fig. 10, 14 and 15, the sanitary washing device according to the present embodiment includes a side portion housing 250 integrally provided to protrude forward on a side portion of the main body 200. The side casing 250 has: a side cover 217 provided at a position forward of the operation unit 210 disposed at the upper portion; and a lotion tank 533 which is built in the forefront part inside the side cover 217 and is constituted by a container that can be visually confirmed. The side casing 250 has a lotion level confirmation window 216 on the front surface thereof, through which the position of the lotion level in the lotion tank 533 can be confirmed.

With this configuration, the user can easily visually confirm the remaining amount of the lotion liquid when using the sanitary washing apparatus or the like. Therefore, the lotion can be replenished before the lotion is used up.

That is, the wash tank 533 has a wash inlet 537 provided with a wash tank cover 536 on the upper side. The lotion tank 533 is provided at the foremost part of the side casing 250, which is forward of the operation portion 210, and is disposed at the position closest to the toilet seat front surface. Therefore, the replenishment of the lotion becomes easy. The side cover 217 is provided at a position forward of the operation unit 210. This prevents the lotion from spilling over the operation unit 210 when the user supplies the lotion to the lotion tank 533. Further, as shown in fig. 14 and 15, the cleaning agent injection port 537 is disposed at a position lower than the operation portion 210. This can more reliably prevent the lotion from spilling over the operation unit 210 when the lotion tank 533 is replenished with the lotion.

In the sanitary washing apparatus of the present embodiment, the lotion pump hose 561 shown in fig. 6 and 14 is formed of a double hose having a hollow cylindrical tube inside and a tube covering the outside of the double hose. In addition, the lotion pump hose 561 has a smaller inner diameter than the foam tank hose 562.

With these configurations, even if a high pressure is applied from the lotion pump 534 to the lotion pump hose 561, the lotion pump hose 561 can be prevented from swelling or breaking. Thereby, the wash foam can be stably spread from the spray nozzle 550 into the toilet bowl.

The lotion pump hose 561 is made of, for example, a double-layer hose in which the outer side of the elastomer resin tube is covered by a heat shrinkable tube portion, but the material is not limited to this. That is, the double-layer hose structure is not particularly limited as long as it can prevent swelling and cracking of the lotion pump hose 561. Thereby, the cleaning foam can be stably dispersed from the dispersing nozzle 550.

As shown in fig. 2, 15, and 16, the sanitary washing apparatus according to the present embodiment includes a control unit 130, a spray nozzle 550, a nozzle device, and the like in a main body 200, and the main body 200 is covered with a main body case 202 on the front surface of a rear main body case 201. In addition, the distribution nozzle 550 is provided in the front portion of the rear main body case 201, and the front and upper portion of the distribution nozzle 550 are covered by the main body case 202. The discharge port 550u at the lower portion of the distribution nozzle 550 is configured to be opened to the toilet bowl inner surface.

The above embodiment is specifically described with reference to fig. 16.

Fig. 16 is a cross-sectional view of the center of the distribution nozzle 550 provided in the rear main body casing 201, taken along the front-rear direction.

In general, the wash foam discharged from the discharge port 550u of the spray nozzle 550 is discharged toward the inner surface of the toilet bowl in the direction indicated by the dotted line T in fig. 16.

However, when the washing is performed in the above-described washing and brushing mode, washing water without washing bubbles is discharged from the discharge port 550u of the spray nozzle 550. In this case, as shown by the two-dot chain line S in fig. 16, the jet flow of the washing water may be diffused and scattered. Therefore, the washing water may be scattered to the outside of the toilet bowl, and the floor surface of the toilet may be wet.

In this embodiment, as shown in fig. 16, the scatter guard 550z is provided in the main body case 202. The splash guard 550z receives a jet flow of wash water or the like in an upward direction from the discharge port 550u of the spray nozzle 550, which exceeds an upper limit (flies outward), and drops the jet flow into the toilet bowl. Thus, the wash foam and wash water discharged from the spray nozzle 550 can be prevented from being discharged to the outside of the toilet bowl, but can be dispersed into the toilet bowl.

The splash guard 550z has the function described below with reference to fig. 17 to 18 in addition to the function of preventing the washing water and the like from being scattered to the outside.

Fig. 17 is a front view of the main body of the sanitary washing apparatus. Fig. 18 is a side view of the main body of the sanitary washing apparatus. Note that the two-dot chain lines shown in fig. 17 and 18 correspond to a placement surface such as a base in a case where the main body 200 is placed.

The main body 200 of the sanitary washing apparatus according to the present embodiment is configured to be attachable to and detachable from the toilet bowl 110 via a main body fixing plate 240 shown in fig. 19.

That is, when a construction worker or a user first sets the main body 200 in the toilet stool, cleans dirt near the lower portion of the back side of the main body 200, and the like, the main body 200 is detached from the toilet stool 110 and placed on a pedestal or the like. The detached main body 200 is sometimes temporarily placed on a pedestal or the ground, for example, lightly.

At this time, the scattering prevention section 550z protects the discharge port 550u of the distribution nozzle 550 located below the mounting surface of the main body 200 from contacting the base or the floor surface temporarily placed thereon. This can prevent damage to the distribution nozzle 550 in advance. That is, as shown in fig. 17 and 18, the spray nozzle 550 has the discharge port 550u prevented from coming into contact with the base by the scatter guard 550 z.

In the above embodiment, the structure in which the scattering prevention section 550z is formed in the main body case 202 has been described as an example, but the present invention is not limited to this. For example, the scattering prevention section 550z may be formed on the main body 550c of the distribution nozzle 550. Thus, a complicated large-sized mold for molding the main body housing 202 is not required, and the main body housing 202 can be molded by a simple mold. Further, the ejection port 550u and the scattering prevention portion 550z can be configured with high positional accuracy.

Next, a structure in which the main body 200 is attachable to and detachable from the toilet bowl 110 will be described with reference to fig. 19.

Fig. 19 is a perspective view of the main body fixing plate 240 and the rear main body case 201 of the main body 200 of the sanitary washing apparatus. For convenience of explanation, fig. 19 illustrates the control unit 130, the distribution nozzle 550, the nozzle device, and the like provided therein in a state where they are omitted.

That is, the main body 200 is fixed to the toilet bowl 110 by inserting a mounting bolt (not shown) into the position adjustment elongated hole 241 of the main body fixing plate 240.

Specifically, first, the center of the body fixing plate 240 and the center of the body 200 in the left-right direction are aligned.

Next, the main body 200 is slid from the toilet bowl surface toward the main body fixing plate 240 in a state where the rear portion of the main body fixing plate 240 is slightly floated. Then, the main body 200 is pushed into the main body fixing plate 240 until a "click" sound is emitted. Thus, the main body 200 and the main body fixing plate 240 are fixed to the toilet bowl 110 by a release (ratchet) mechanism.

On the other hand, when the main body 200 is detached from the toilet bowl 110, the main body attachment/detachment button 242 in the lateral direction (side surface) of the main body 200 shown in fig. 19 is pushed into the back (inside) with a finger or the like, for example. Then, the main body 200 is pulled out forward while being pushed in. Thereby, the main body 200 can be detached from the toilet bowl 110.

As described above, the main body 200 and the toilet bowl 110 are configured to be detachable.

As shown in fig. 19, a magnet 243 is embedded in a body fixing plate 240 made of resin such as polypropylene (PP), and a detachable sensor 244 is attached to the rear body case 201. This enables detection of the state of attachment/detachment of the main body 200 and the toilet bowl 110.

The attachment/detachment sensor 244 is constituted by, for example, a reed switch.

The detection of the attached/detached state by the attached/detached sensor 244 will be described below with reference to fig. 20.

Fig. 20 is a partial sectional view showing a state where the main body 200 is fixed to the main body fixing plate 240 of the sanitary washing apparatus.

As shown in fig. 20, when the main body 200 is mounted on the toilet bowl 110, the magnet 243 of the main body fixing plate 240 and the attachment/detachment sensor 244 of the rear body casing 201 are disposed in a positional relationship of facing each other in proximity. At this time, the reed switch as the detachable sensor 244 is turned ON (ON) by the magnetic force of the magnet 243. This makes it possible to detect that the main body 200 is mounted on the toilet bowl 110.

On the other hand, when the main body 200 is detached from the toilet 110, the magnet 243 is separated from the attachment/detachment sensor 244, and the reed switch is turned OFF (OFF). Thus, the detachable state of the main body 200 and the toilet 110 can be detected by the detachable sensor 244.

In the sanitary washing apparatus according to the present embodiment, when the detachable sensor 244 detects that the main body 200 is detached from the toilet 110, the control unit 130 controls not to perform the discharge operation of the spray nozzle 550. Therefore, in a state where the main body 200 is detached from the toilet bowl 110, even if the user presses a button such as the manual bubble coverage switch 433 or the manual splash prevention switch 434 of the remote controller main body 401, for example, the control part 130 does not perform the discharge operation from the spray nozzle 550. This makes it possible to prevent a problem such as accidental discharge of the washing water or the washing foam to the floor or the person.

On the other hand, when the attachment/detachment sensor 244 detects that the main body 200 is detached from the toilet 110, the control unit 130 also controls the ejection operation of the hip-wash nozzle 831 and the private parts-wash nozzle 832 to be prohibited. This is because, if the attachment/detachment sensor 244 should fail, the control unit 130 may erroneously recognize that the main body 200 has been detached from the toilet bowl 110. Therefore, the control part 130 controls to be able to perform the hip washing and the female private parts washing as the basic functions of the sanitary washing apparatus. This can suppress a reduction in convenience for the user.

As described above, the control unit 130 controls the sanitary washing apparatus based on the detection of the attachment/detachment state by the attachment/detachment sensor 244.

The operation and control of each part when the sanitary washing apparatus of the present embodiment rotationally disperses the foam will be described below with reference to fig. 21.

As shown in fig. 21, at a time N1, the user presses the manual foam cover switch 433 of the remote controller main body 401. Thus, the control unit 130 rotates the lotion pump 534 in the reverse direction at time N2, for example, for 2 seconds, and then rotates the lotion pump 534 in the normal direction at time N3. At the same time, the control unit 130 starts the operation of the water pump 516 and the air pump 535 at time N3. Thereby, the lotion, water, and air are supplied into the bubble tank 532, thereby generating the cleansing bubbles.

The generated wash foam is rotationally dispersed from the spouting port 550u of the dispersion nozzle 550 to the inner surface of the toilet bowl. As a result, adhesion of dirt to the inner surface of the toilet bowl can be suppressed, and the dirt can be easily removed.

At this time, the discharge port 550u of the spray nozzle 550 is driven to rotate by the spray nozzle driving portion 550a, which is, for example, a stepping motor. Specifically, the foam is dispensed from the discharge port 550u while being normally rotated from the stop position at time N3 (20 ° in fig. 11) to the endmost position at time N6 (340 ° in fig. 11) in fig. 21. Then, the foam is dispersed while reversing from the endmost position at time N6 to the stop position at time N9, and then returned.

At time N11, the controller 130 automatically stops the operation of the water pump 516 and the air pump 535, for example, by timer control. Thereby, the rotational dispersion of the foam is automatically ended.

At this time, the controller 130 continuously operates the water pump 516 and the air pump 535 between the time N3 and the time N11 when the foam is rotationally dispensed. On the other hand, the control unit 130 intermittently operates the wash pump 534 so that it is normally rotated and then stopped during the period from the time N3 to the time N4, the period from the time N6 to the time N7, and the period from the time N9 to the time N10.

The intermittent operation is based on the following results obtained by experiments: in the rotary dispersion foam, the lotion, water and air are efficiently mixed, and the cleaning foam can be generated more stably. By the intermittent operation of the lotion pump 534, the cleansing foam can be stably generated. As a result, wasteful use of the lotion can be prevented, and the trouble of replenishing the lotion can be reduced.

In the sanitary washing apparatus according to the present embodiment, the intermittent operation of the lotion pump 534 is set to be, for example, 2 seconds in a cycle of 6 seconds.

In the timing chart shown in fig. 21, the operation of the heat exchanger 700 is depicted by a broken line in order to show that the operation is performed as needed. This is because, when the water supplied from the water pump 516 to the foam tank 532 is lower than 20 ℃, the wash foam may not be stably generated when the foam is rotationally dispersed. When the water temperature is low, the heat exchanger 700 performs heating control to heat the washing water so that the water temperature becomes, for example, about 20 ℃. The operation is shown in the case where heated washing water is supplied to the bubble tank 532. This prevents the foaming property from being lowered, and thus, an ideal cleaning foam can be generated and supplied to the foam tank 532.

In addition, in the time chart shown in fig. 21, the lotion pump 534 is reversed from the time N2 immediately before the time N3 at which the rotation to disperse the foam is started to the time N3. This is because the lotion pump 534 employs a tube pump in the present embodiment. A tube pump for delivering the lotion in the tube by the pushing action of the roller. Therefore, the reverse rotation operation immediately before causes the lotion to flow backward from the outlet side of the tube to the pushed-out tube portion, and the pushed-out portion returns to a cylindrical shape. Then, the lotion pump 534 is rotated forward with the shape of the tube restored. This enables a stable amount of the lotion to be delivered to the spray nozzle 550.

As shown in the timing chart of fig. 21, the controller 130 returns the spray nozzle driving unit 550a from the stop position to the original position from time N11 to time N14. Specifically, the distribution nozzle driving unit 550a is driven until it comes into contact with the origin position. At this time, the spray nozzle driving unit 550a presses the rotation detection microswitch disposed at the origin position. Thereby, the control unit 130 recognizes the origin position of the distribution nozzle driving unit 550a configured by the stepping motor. Then, the control section 130 drives the scattering nozzle driving section 550a to return to the stop position. This is because the stepping motor sometimes causes a slip phenomenon due to, for example, an increase in some rotational load. Therefore, the rotational driving corresponding to the number of driving steps cannot be performed, and the number of driving steps and the amount of rotation deviate. Therefore, as described above, the reset operation of the distribution nozzle driving unit 550a to the origin position is performed. This allows the stop position, which is the start position for the rotation of the dispensing nozzle driving unit 550a to dispense the foam, to be returned to the correct position, and the driving can be started. As a result, the rotation angle of the distribution nozzle 550 can be accurately defined with reference to the origin position of the distribution nozzle driving unit 550a, and the rotating distribution of the foam can be always performed at a stable position.

In addition, for example, the detergent adheres to the periphery of discharge port 550u of dispensing nozzle 550 for some reason, and dispensing nozzle drive unit 550a may not be rotationally driven. In this case, by detecting whether or not the microswitch is turned on or off by the rotation pressed by the reset operation of the spray nozzle driving unit 550a to the origin position, it is possible to easily detect a failure of the spray nozzle driving unit 550 a.

When the on signal is not input from the rotation detection microswitch at the time of rotating the dispensed foam, the following lighting display is performed by the wash lamp 223a (see fig. 4) disposed in the operation unit 210, thereby notifying the user of a trouble. Accordingly, the user can be prompted to operate the wash switch 223 to perform the washing operation.

In the sanitary washing apparatus according to the present embodiment, the time from the time N3 when the rotation of the foam is started to the time N12 when the rotation is ended, which is shown in the time chart of fig. 21, is set to about 15 seconds, for example. Further, about 15 seconds is an example, and may be changed to, for example, about 10 seconds or about 25 seconds depending on the size of the toilet bowl, etc.

Here, the lighting display of the wash lamp 223a will be specifically described.

When the time until the rotation detection microswitch is pressed is delayed by, for example, about 10% or more from the rotation foam dispensing time set as described above, the wash lamp 223a is lighted and displayed so as to perform a flashing operation such as "flashing once" and "flashing once" repeatedly. Thereby, the user is prompted to press the wash switch 223 to perform the washing operation.

The washing operation flows the washing water heated to about 40 c by the heat exchanger 700 to the foam generating part 560 and the spray nozzle 550 and washes for about 3 minutes, for example. The foam generating unit 560, the spray nozzle 550, and the like are washed with heated washing water by the washing operation. As a result, the lotion can be prevented from adhering to or clogging the foam generating section 560, the dispensing nozzle 550, and the like, and the dispensing foam can be rotated stably.

In the above state, when the washing operation is not performed, the detergent or the like is solidified on the spray nozzle 550, and the operation is deteriorated. In this case, when the time until the rotation detection microswitch is pressed is delayed by, for example, about 20% or more from the set rotation foam dispensing time, the wash lamp 223a is lighted and displayed so as to repeat the blinking operation twice as "one flash, one flash", "one flash, and one flash". This prompts the user to perform a brushing operation by pressing the brushing switch 223 and to perform cleaning by brushing the vicinity of the discharge port 550u of the brush nozzle 550 with a toothbrush or the like.

By lighting the wash lamp 223a as described above, the user can be reminded of the response based on the detection of the malfunction of the spray nozzle driving unit 550 a.

In the time chart of flow channel switching shown in fig. 21, the following operations are shown: at times N2 to N3, the supply destination of the washing water from the water pump 516 of the water circuit shown in fig. 6 is switched from the nozzle device 800 side to the bubble generating unit 560 side. Further, the operation of switching the supply destination of the washing water from the bubble generation unit 560 side to the nozzle device 800 side at the time points N11 to N13 is shown.

Specifically, at time N2 to N3, the flow control valve 517 is closed and the opening/closing valve 530a is opened, so that the supply destination of the washing water is switched to the bubble generation unit 560. On the other hand, at times N11 to N13, the opening/closing valve 530a is closed and the flow control valve 517 is opened, so that the supply destination of the cleaning water is switched to the nozzle device 800.

In the above, the opening/closing valve 530a is described as an example, but is not limited thereto. For example, the flow path may be switched by a flow path switching valve such as a three-way valve disposed at a branch point where the branch flow path 530 branches from the wash water supply flow path 690.

The action and control of the various parts in the sanitary washing apparatus when rotating to distribute the foam is performed as described above.

The operation and control of each part during the scrub operation in the sanitary washing apparatus will be described below with reference to fig. 22.

Fig. 22 is a time chart during the wash operation in the sanitary washing apparatus.

As shown in fig. 22, at time N1, when the user presses the wash switch 223 of the operation unit 210, the control unit 130 sets the wash and issue mode. Thus, the controller 130 switches the supply destination of the cleaning water from the nozzle device 800 side to the bubble generating unit 560 side at times N2 to N3. Then, during about 2 minutes from time N3 to N8, the wash water warmed to about 40 ℃ by heat exchanger 700 is sent to foam tank 532 by water pump 516 with wash pump 534 stopped. The transferred wash water is sprayed from the spray nozzle 550 into the toilet bowl.

Subsequently, the controller 130 operates the air pump 535 for about 1 minute from the time N8 to the time N10. Thus, along with the washing water warmed to about 40 ℃, the air pump 535 is used to supply air into the bubble box 532 while performing the washing and brushing.

That is, in the scrub operation of the scrub washing, only the washing water is first supplied to the bubble tank 532. Then, the air pump 535 is operated from the middle of the water supply, and the foam tank 532 is washed while adding air. Thus, a large amount of the detergent component remaining in the bubble tank 532 and the flow path is first discharged from the spray nozzle 550 into the toilet bowl quickly and efficiently by the washing water. Then, the air is supplied into the foam tank 532 while adding the momentum of the air bubbles (air) generated by the air pump 535. In this case, the bubbles act to wash even a trace amount of the remaining lotion component. As a result, effective washing and rinsing can be performed in a short time.

When the above-described washing and rinsing for about 3 minutes is completed, controller 130 rotates wash pump 534 forward and backward at times N10 to N14. Thereby, the lotion pump 534 is put into a standby operation state so that the next rotation dispensing foam or fixed dispensing foam can be started normally. The control unit 130 automatically ends the washing operation by timer control, for example.

The operation and control of each part during the washing operation in the sanitary washing apparatus are performed as described above.

The operation and control of each part when the foam is fixed and dispersed in the sanitary washing apparatus will be described below with reference to fig. 23.

Fig. 23 is a time chart of the fixed dispersion foam in the sanitary washing apparatus.

As shown in fig. 23, at time N1, when the user presses the manual splash guard switch 434 of the remote controller main body 401, the control unit 130 sets the fixed dispersed foam starting mode (foam covering mode). Thus, at time N2, after the control unit 130 rotates the lotion pump 534 in the reverse direction for 2 seconds, the lotion pump 534 is rotated in the normal direction at time N3. Further, the control unit 130 starts the operation of the water pump 516 and the air pump 535 at time N3. Thereby, the lotion, water, and air are supplied into the bubble tank 532, thereby generating the cleansing bubbles.

The generated wash foam is spread from the spouting port 550u of the spreading nozzle 550 to the inner surface of the toilet bowl. At this time, the fixed dispersion foam for dispersing the washing foam into the inner surface of the toilet bowl accumulates and covers the water surface of the toilet bowl with the foam having a foam height of about 10mm (see fig. 25). In addition, splash of urine, for example, when a man urinates, is suppressed by the cushioning effect of the cleansing foam.

In the time chart of fig. 23 when the foam is fixedly dispensed and the time chart of fig. 21 when the foam is rotationally dispensed, the movement of the ejection port 550u of the dispensing nozzle 550 is different.

That is, in the case of rotationally dispensing foam as shown in fig. 21, the discharge port 550u of the dispensing nozzle 550 is rotationally driven by the dispensing nozzle driving portion 550 a. On the other hand, in the case of performing the fixed dispersion foam shown in fig. 23, the difference is that the dispersion nozzle driving portion 550a disperses the cleaning foam in a state where the discharge port 550u of the dispersion nozzle 550 is fixed without being driven to rotate.

The timing chart shown in fig. 23 other than the above is the same as the timing chart shown in fig. 21. Therefore, redundant description with fig. 21 is omitted.

Here, the origin position, the stop position, and the extreme end position of the spray nozzle driving unit 550a shown in the timing charts of fig. 21 to 23 are described by taking the angular position shown below as an example, but not limited thereto.

That is, although the description has been given by taking as an example a case where the origin position is the position of 0 ° (right back) shown in fig. 11, the stop position is the position of 20 ° (clockwise rotation) shown in fig. 11, and the end position is the position of 340 ° (clockwise rotation) shown in fig. 11, the present invention is not limited to this. For example, the origin position may be a position of 5 ° (clockwise rotation from right behind). The stop position may be a position of 60 ° (clockwise rotation from right behind). Further, the end position may be 300 ° (clockwise rotation).

Next, the operation of fixing the dispersed foam shown in fig. 23 when the stop position is set to 60 ° will be described.

First, when the fixed dispersed foam starting mode is set, the control portion 130 immediately performs fixed dispersed foam in a state where the direction of the ejection port 550u is stopped at a stop position rotated by about 60 ° clockwise from the right rear by the dispersing nozzle driving portion 550 a.

At this time, the control unit 130 drives the spray nozzle driving unit 550a to cause the discharge port 550u to wait in advance at a position of about 60 ° as a stop position. Then, when the fixed dispersion foam is instructed in the standby state, the control part 130 immediately discharges the wash foam to the inner surface of the toilet stool without moving the dispersion nozzle 550. Thus, before the man's urination starts, a foam film having a foam height necessary for suppressing splashing is rapidly formed on the water surface in the toilet bowl.

In this case, the following effects can be obtained particularly when the direction of the stop position of the discharge port 550u is set to the position of 50 ° to 70 ° (about 60 °). That is, when the wash foam is discharged at the stop position, the wash foam contacts the inclined surface of the inner surface of the toilet bowl. The wash foam contacting the slope surface flows down toward the water surface near the discharge port 115 in a manner of rotating on the slope surface of the inner surface of the toilet bowl. Thereby, a foam film of the cleansing foam can be formed in a short time over the entire water surface.

In the present embodiment, the structure in which the manual foam-covering switch 433 of the remote controller main body 401 is pressed to rotate and dispense the foam shown in fig. 21 is described as an example, but the present invention is not limited thereto. For example, it may be set such that the rotating spreading of the foam is automatically performed after the toilet is used. Further, it may be set such that the rotating distribution of the foam is automatically performed at regular intervals. This makes it possible to further prevent the adhesion of dirt to the inner surface of the toilet bowl and to remove the dirt more easily.

In addition, by automatically rotating and spreading the foam at regular intervals, the formation of dirt, particularly a ring mark, near the waterline in the toilet bowl can be effectively suppressed.

At this time, in the case where the rotation for dispensing the foam is performed in the automatic operation after the toilet is finished, the sanitary washing apparatus according to the present embodiment is set to rotate for dispensing the foam for about 15 seconds after the seating sensor 330 detects that the user stands up from the toilet seat 300, for example, for about 60 seconds.

On the other hand, in the case where a man who is not seated on the toilet seat urinates, it is set that the rotation for spreading the foam is performed for about 15 seconds, for example, after about 60 seconds after the toilet seat opening/closing sensor 331 detects that the toilet seat 300 is closed.

Further, although the example in which the rotation is performed to disperse the foam after about 60 seconds after the sensor sensing is described above, it is not limited thereto. The switch of the remote control main body 401 can be arbitrarily changed to, for example, approximately 10 seconds later, 25 seconds later, or the like. Thus, the time until the start of rotating the foam can be adjusted to any time according to the user's mode of use.

In addition, although the description has been made in the above as an example of the time for rotationally spreading the foam is about 15 seconds, it is not limited thereto. The switch of the remote controller main body 401 can be arbitrarily changed to, for example, 10 seconds or 25 seconds. Thus, the amount of foam to be dispersed can be arbitrarily adjusted according to the size of the toilet bowl and the like.

In the present embodiment, the structure in which the fixed scattering foam shown in fig. 23 is executed when the manual splash guard switch 434 of the remote controller main body 401 is pressed has been described as an example, but the present invention is not limited to this. For example, it may be set such that the fixed dispersion foam is automatically performed when the toilet seat is opened. Thus, when the toilet seat 300 is opened while a man urinates, the fixed dispersion foam is automatically performed. As a result, the splash of urine can be effectively suppressed when a man urinates.

Further, it is configured that, in the case where it is set to fix the dispersed foam by the automatic operation when the toilet seat is opened, the fixed dispersed foam is performed for, for example, about 15 seconds immediately after the toilet seat 300 is opened.

Further, although the description has been made in the above as an example of fixing the time for spreading the foam for about 15 seconds, it is not limited thereto. The switch of the remote controller main body 401 can be arbitrarily changed to, for example, 10 seconds or 25 seconds. Thus, the amount of foam to be dispersed can be arbitrarily adjusted according to the size of the toilet bowl and the like.

The action and control of the parts in the sanitary washing apparatus in fixing the dispersed foam are performed as described above.

Hereinafter, the following description will be given of a configuration of the automatic operation for selecting and setting the above-described fixed dispersed foam or the rotary dispersed foam in the sanitary washing apparatus, with reference to fig. 24.

Fig. 24 is a diagram illustrating selection settings of automatic operation when the fixed distribution foam and the rotating distribution foam are applied to the sanitary washing apparatus.

Further, with regard to the automatic operation at the time of fixing the dispersed foam and rotating the dispersed foam, the favorite setting can be selected each time the automatic selection setting switch 236 of the operation portion 210 is pressed.

Specifically, as shown in the left side of fig. 24, the automatic selection setting switch 236 is disposed in the operation unit 210 in parallel with the operation switch 220. An automatic rotation dispensing lamp 236a after use, an automatic rotation dispensing lamp 236b at regular intervals, and an automatic fixation dispensing foam display lamp 236c when the toilet seat is turned on are disposed beside the automatic selection setting switch 236. Each time the automatic selection setting switch 236 is pressed, the lamps are lighted and displayed in the order of the direction indicated by the arrow in the right drawing of fig. 24. Thus, three kinds of automatic operation can be set in an arbitrary combination according to the preference of the user.

Specifically, H0 shows that the automatic rotating and dispensing lamp 236a, the automatic rotating and dispensing lamp 236b at regular intervals after use, and the automatic fixed and dispensing foam indicator lamp 236c are all in the light-off state when the toilet seat is turned on. That is, H0 indicates that all three automatic operations are in the "off" state.

When the automatic selection setting switch 236 is pressed once from the state of H0, only the automatic rotation scattering lamp 236a is turned on after use, and the state becomes H1. That is, every time the automatic selection setting switch 236 is pressed, the setting is switched to the state of H2, H3... H6. When the automatic selection setting switch 236 is pressed once from the state of H6, all of the three types of automatic operation are in the on state of H7. In the lamp display of fig. 24, the o mark indicates an off state corresponding to the light-off state, and the ● mark indicates an on state corresponding to the light-on state.

For example, in the case of the states of H2, H4, H6, H7 shown in fig. 24 which are set to rotate the dispersed foam by automatic operation at regular intervals, the rotation dispersed foam explained using the time chart of fig. 21 is automatically executed, for example, at approximately 3 hours. This can suppress the formation of dirt, particularly a ring mark, in the vicinity of the waterline in the toilet bowl.

The setting performed every approximately 3 hours described above can be changed to any setting such as every approximately 6 hours, every approximately 12 hours, or every approximately 24 hours by the switch of the remote controller main body 401. Thus, the number of times of automatic operation can be reduced when the user is absent for a long time, and the adjustment can be made arbitrarily according to the situation of the user.

The automatic operation settings of the fixed dispersion foam and the rotating dispersion foam are selected and executed as described above.

(embodiment mode 2)

The sanitary washing device according to embodiment 2 will be described below with reference to fig. 27 and 28.

Fig. 27 is a perspective view of the sanitary washing apparatus according to embodiment 2. Fig. 28 is a schematic diagram showing a cross section of a main part of the sanitary washing device of the embodiment.

As shown in fig. 27 and 28, the sanitary washing apparatus according to the present embodiment is a so-called toilet-integrated sanitary washing apparatus 1000 in which the toilet bowl 110 and the main body 200 are integrated.

In fig. 27, the toilet seat 300 and the seating sensor 330 shown in fig. 1, which have been described in embodiment 1, are not shown in order to explain the structure inside the toilet bowl 110. However, the sanitary washing apparatus 1000 shown in fig. 27 similarly includes a toilet seat and a seating sensor.

That is, the sanitary washing apparatus 1000 of the present embodiment is different from the sanitary washing apparatus 100 of the so-called rear mount type in which the main body 200 is provided on the toilet bowl 110 from the rear as described in embodiment 1. Since the basic configuration and function are the same as those of the sanitary washing apparatus 100 according to embodiment 1, the same components are denoted by the same reference numerals, and detailed description thereof is omitted. For example, the sanitary washing apparatus 1000 has a configuration for performing the foam scattering operation, as in the sanitary washing apparatus 100 according to embodiment 1.

Specifically, the sanitary washing apparatus 1000 is different from the sanitary washing apparatus 100 according to embodiment 1 in that: the sanitary washing apparatus 1000 further includes a toilet washing remote controller 900 provided with a flush switch 910, and a toilet washing flow path 920.

One end of the toilet bowl washing flow path 920 is connected to, for example, an external water supply connection port (see fig. 6). The other end of the toilet bowl washing flow path 920 is provided with a toilet bowl water outlet 940. The toilet bowl water outlet 940 is provided near the rim 950 located at the front position around the rear 1/3 on the right side of the toilet bowl upper portion, for example.

Further, the toilet bowl cleaning flow path 920 includes a flush valve 930 in the middle. The flush valve 930 opens and closes the toilet bowl cleaning flow path 920 in response to a signal from the flush switch 910. At this time, when the flush valve 930 is opened, for example, water supplied from the outside is ejected from the toilet bowl outlet 940 near the rim 950 so as to follow the inner circumference of the toilet bowl 110. Thus, the toilet after defecation can be flushed or flushed.

The sanitary washing apparatus 1000 is configured as described above.

The following description mainly deals with operations and actions of the sanitary washing apparatus 1000 different from those of the sanitary washing apparatus 100 according to embodiment 1.

First, after using the toilet, for example, the user presses the flush switch 910. At this time, the on signal of the flush switch 910 is inputted to the control unit 130 in the main body 200 via an infrared ray, for example. The control unit 130 opens the flush valve 930 of the toilet bowl washing flow path 920 in response to the input on signal. Accordingly, the toilet outlet 940 of the toilet cleaning flow path 920 discharges water along the inner circumference of the toilet 110 in the vicinity of the rim 950 of the toilet upper portion. The sprayed water flows around the rim 950 of the upper part of the toilet bowl to the lower part of the toilet bowl and is discharged through the toilet bowl drain 960.

At this time, the controller 130 of the sanitary washing apparatus 1000, when washing the toilet bowl by discharging water from the toilet bowl outlet 940, discharges washing foam toward the discharge port 550u of the spray nozzle 550, for example, toward the water discharged from the vicinity of the toilet bowl outlet 940.

That is, the cleansing foam is ejected from the ejection port 550u of the spray nozzle 550 toward the water near the toilet bowl water outlet 940 that is ejected from the toilet bowl water outlet 940. This makes it possible to forcibly flush the toilet bowl with the water mixed with the wash foam to a position in the vicinity of the rim 950 of the toilet bowl upper portion, which is not sufficiently reached by only the foam dispensing from the dispensing nozzle 550.

Specifically, the water discharged from the toilet outlet 940 rotates along the inner circumference of the toilet in the vicinity of the rim 950 of the upper part of the toilet and gradually flows to the lower part of the toilet.

At this time, the control portion 130 spreads the cleansing foam from the discharge port 550u of the spray nozzle 550 toward the water near the discharged toilet bowl water outlet 940. Thereby, the wash foam is mixed with the water sprayed from the toilet bowl water outlet 940. Then, the water mixed with the cleansing foam gradually flows to the lower portion of the toilet while revolving along the inner circumference of the toilet 110 near the rim 950 of the upper portion of the toilet. Therefore, the water mixed with the cleansing foam spreads widely from the vicinity of the rim 950 of the toilet upper portion to the lower portion of the toilet where the toilet drain 960 is located. Thus, the inner surface of the toilet can be cleaned more reliably without cleaning unevenness by the water mixed with the cleaning foam. As a result, the generation of fouling and the like can be effectively suppressed.

In embodiment 2, the structure in which the wash foam is ejected from the spray nozzle 550 toward the water in the vicinity of the toilet bowl water outlet 940 when the toilet bowl is washed has been described as an example, but the invention is not limited thereto. For example, the water may be discharged from the toilet bowl outlet 940 while spreading the cleansing foam on the inner surface of the toilet bowl, without being limited to the vicinity of the toilet bowl outlet 940.

In embodiment 2, the timing of spreading the cleansing foam from the spreading nozzle 550 toward the water in the vicinity of the toilet bowl water outlet 940 is not particularly mentioned, but may be performed at the following timing.

For example, the wash foam may be dispensed from the dispensing nozzle 550 at the same time that water is ejected from the bowl outlet 940. Alternatively, the cleansing foam may be dispensed from the dispensing nozzle 550 after a time lag is set after the water starts to be discharged from the toilet bowl water outlet 940. The same effect can be obtained by forcibly flushing the inside of the toilet bowl with the water mixed with the cleansing foam in a widely distributed manner at any one time.

Further, the control unit 130 may be such that: when the on signal of the flush switch 910 is input to the control part 130, the control part 130 first spreads the wash foam from the spreading nozzle 550 to the entire surface or a part of the inner surface of the toilet stool. Then, the control part 130 opens the flush valve 930 to discharge the water from the toilet outlet 940. At this time, the control part 130 may further continuously or intermittently distribute the wash foam from the distribution nozzle 550 to the inner surface of the toilet stool 110 or the water near the toilet stool outlet 940 to wash the toilet stool 110. Thereby, a higher cleaning effect can be obtained.

Although not particularly described in embodiment 2, the control unit 130 may perform the following operations after the toilet bowl is washed after the toilet is discharged.

Specifically, after the toilet bowl is washed after the defecation, the control part 130 closes the flush valve 930. In this state, the control unit 130 performs a rotating foam spreading operation for spreading the cleansing foam into the toilet bowl while rotating the discharge port 550u of the spreading nozzle 550 in the same direction as in embodiment 1. Thus, after the toilet bowl is washed, a foam film is formed on the inner surface of the toilet bowl from the front to the rear in advance. As a result, adhesion of dirt can be effectively suppressed.

In embodiment 2, the toilet cleaning is performed after the user operates the flush switch 910 of the toilet cleaning remote controller 900, but the present invention is not limited thereto. For example, when the seat sensor (not shown) detects that the user is out of the seat from the toilet seat (not shown), the toilet bowl may be automatically cleaned after a predetermined time, for example, 30 seconds. This can reliably prevent the user from forgetting to wash the toilet bowl. Further, the toilet cleaning remote controller 900 may not be separately provided.

Specifically, the sanitary washing apparatus 1000 of the present embodiment includes a seating sensor (see fig. 1) that detects whether or not a user is seated on a toilet seat (see fig. 1), as described in embodiment 1. Therefore, when the seating sensor detects that the user is out of the seat from the toilet seat, the toilet bowl washing may be automatically performed.

In the above, the toilet cleaning is started after a predetermined time, for example, about 30 seconds, but the toilet cleaning may be started after detection of the user's absence, for example, about 20 seconds, or 60 seconds. That is, the predetermined time of 30 seconds is merely an example, and is not particularly limited.

According to the above-described structure, even if the user forgets to operate the flush switch 910 of the toilet cleaning remote controller 900 after toileting, toilet cleaning is automatically performed. Therefore, the toilet stool 110 can be always maintained in a clean state.

It is also preferable that the control unit 130 is configured not to automatically perform toilet cleaning even if it is detected that the user is out of the seat from the toilet seat when the user operates the flush switch 910 to instruct toilet cleaning before the predetermined time elapses. Thereby, repeated toilet cleaning can be avoided. Therefore, wasteful use of lotion or the like used for foam spreading can be prevented.

In embodiment 2, the flush switch 910 is provided in the remote controller for toilet cleaning 900 separately from the remote controller 400, but the present invention is not limited thereto. For example, the flush switch 910 may be provided on the remote controller 400. This can simplify the structure. In addition, the beauty in the toilet room is improved.

In embodiment 2, the configuration in which the operation unit described in embodiment 1 is not provided in the main body has been described as an example, but the present invention is not limited to this. For example, the main body 200 may be integrally provided with an operation portion, and the flush switch 910 may be provided in the operation portion. This improves the operability and the like.

As described above, the sanitary washing apparatus 1000 of the present embodiment includes: a flush switch 910; and a toilet bowl washing flow path 920 including a flush valve 930 opened and closed by a signal of the flush switch 910, and having a toilet bowl outlet 940 disposed near a rim 950 of the toilet bowl upper portion. The sanitary washing device 1000 further includes: a toilet bowl 110 which discharges water discharged from a toilet bowl outlet 940 through a toilet bowl outlet 960 at a lower part of the toilet bowl while turning around a rim 950 at an upper part of the toilet bowl; a main body 200 provided on the toilet bowl 110; and a foam generating part 560 that generates a cleaning foam. The sanitary washing device 1000 further includes: a spray nozzle 550 for spraying washing water or washing foam to the inner surface of the toilet bowl; a dispensing nozzle driving part 550a that drives the dispensing nozzle 550; and a control section 130. The control unit 130 is configured to, when the flush valve 930 is opened by an on signal of the flush switch 910 and water is discharged from the toilet bowl outlet 940 to the vicinity of the rim 950 of the toilet bowl upper portion, discharge wash foam from the spray nozzle 550 toward the inner surface of the toilet bowl 110 or the water in the vicinity of the toilet bowl outlet 940. Thus, the water mixed with the washing foam can be spread over a wide area in the toilet bowl, and the inner surface of the toilet bowl can be washed uniformly. As a result, fouling can be suppressed.

Further, the control unit 130 of the sanitary washing apparatus 1000 according to the present embodiment is configured to rotationally dispense the wash foam to the toilet bowl inner surface in the direction of driving the discharge port 550u of the dispensing nozzle 550 in the state where the flush valve 930 is closed after the toilet washing is finished. Thus, after the toilet bowl is cleaned, a foam film is formed on the inner surface of the toilet bowl in advance. As a result, the adhesion of dirt to the toilet bowl 110 can be suppressed.

As described above, the sanitary washing apparatus of the present invention includes: a flushing switch; and a toilet bowl washing flow path including a flush valve that is opened and closed by a signal of a flush switch, and having a toilet bowl outlet disposed near a rim of an upper portion of the toilet bowl. Further, the sanitary washing device includes: a toilet bowl which discharges water ejected from a toilet bowl water outlet at the lower part of the toilet bowl while rotating near a rim at the upper part of the toilet bowl; a main body provided on the toilet bowl; and a foam generating part that generates a cleaning foam. Further provided with: a spray nozzle which sprays washing water or washing foam to an inner surface of the toilet bowl; a dispensing nozzle driving section that drives the dispensing nozzle; and a control section. The control unit is configured to eject the wash foam from the spray nozzle toward the inner surface of the toilet bowl or the water near the toilet bowl outlet when the flush valve is opened by an on signal of the flush switch and the water is ejected from the toilet bowl outlet to the vicinity of the rim at the upper part of the toilet bowl.

According to this configuration, the control unit opens the flush valve after defecation to discharge water from the toilet outlet of the toilet bowl washing flow path to the inner surface of the toilet bowl. At this time, the control portion ejects the washing foam from the spray nozzle toward the water near the ejected toilet bowl outlet. Thereby, the water and the cleaning foam are mixed. Then, the water mixed with the cleansing foam turns around the rim of the upper portion of the toilet bowl in the toilet bowl and flows to the lower portion of the toilet bowl. Thus, the water mixed with the cleansing foam spreads over a wide area in the toilet bowl. As a result, the inner surface of the toilet bowl can be cleaned uniformly and more reliably.

In the sanitary washing apparatus according to the present invention, the control unit may be configured to rotationally drive the discharge port of the discharge nozzle in a direction to discharge the wash foam to the inner surface of the toilet bowl in a state where the flush valve is closed after the toilet bowl washing is completed.

According to this structure, after the toilet bowl is cleaned, a foam film is formed in advance on the inner surface of the toilet bowl. Thereby, attachment of dirt to the toilet bowl inner surface can be suppressed.

The sanitary washing device of the present invention may further include a toilet washing remote controller, and the flush switch may be provided in the toilet washing remote controller.

In addition, the sanitary washing apparatus of the present invention may further include a remote controller, and the flush switch may be provided on the remote controller.

The sanitary washing device of the present invention may further include an operation unit provided integrally with the main body, and the flush switch may be provided on the operation unit.

The toilet lid of the sanitary washing apparatus according to the present invention may be configured to include a seating sensor for detecting the seating or unseating of a user, and when the seating sensor detects the unseating of the user and the control unit does not input an on signal of the flush switch for a predetermined time, the flush valve may be opened after the predetermined time has elapsed, and water may be supplied from the toilet outlet to the inner surface of the toilet to wash the toilet. Thus, forgetting to clean the toilet seat can be reliably prevented.

The spray nozzle of the sanitary washing apparatus according to the present invention is provided in the main body such that the rotation axis of the discharge port of the spray nozzle which is rotationally driven is inclined in the front-rear direction and the left-right direction. The inclination in the front-rear direction may be such that the lower side of the spray nozzle is inclined toward the front of the toilet bowl with respect to the rotational axis, and the inclination in the left-right direction may be such that the lower side of the spray nozzle is inclined toward the cleaning nozzle with respect to the rotational axis.

According to this configuration, when the toilet foam for spreading the wash foam to the toilet is spread, the direction of the discharge port is raised when the discharge port of the spreading nozzle is directed to the spreading position in front of the toilet at a long distance. On the other hand, when the discharge port of the discharge nozzle is directed to the discharge position at the rear of the toilet bowl at a short distance, the direction of the discharge port is lowered. Thereby, the washing foam can be spread while changing the height of the discharge port of the spreading nozzle according to the distance from the discharge port of the spreading nozzle to the inner surface of the toilet bowl. Therefore, the wash foam can be spread on the inner surface of the toilet bowl from the front to the rear, thereby forming the foam film. As a result, the adhesion of dirt to the inner surface of the toilet bowl can be suppressed.

In addition, the control unit of the sanitary washing apparatus according to the present invention may control the step of rotationally spreading the foam by at least one of the following reciprocating rotational actions when rotationally spreading the foam from the spreading nozzle to the toilet bowl: the control portion rotates the spray nozzle driving portion in the forward direction, and the direction of the spray nozzle is rotated from the rear of the toilet bowl to the rear of the toilet bowl through the front of the toilet bowl.

According to this configuration, the control unit first rotates the dispensing nozzle driving unit forward, moves the direction of the discharge port of the dispensing nozzle from the toilet bowl rear to the toilet bowl rear through the toilet bowl front, and dispenses the cleansing foam. Then, the control part reverses the spraying nozzle driving part, moves the direction of the spraying nozzle in the direction from the rear of the toilet bowl to the rear of the toilet bowl through the front of the toilet bowl, and simultaneously sprays the cleaning foam. That is, the cleansing foam is spread over the inner circumferential surface of the toilet bowl by at least one reciprocating rotational drive while rotationally moving the direction of the discharge port 550u of the spray nozzle 550 in the forward and reverse directions. Thus, the output of the water discharge amount variable portion is controlled so that the wash foam reaches the vicinity of the rim of the toilet bowl, and the wash foam can be spread over substantially the entire circumference of the inner surface of the toilet bowl. As a result, a foam film is formed on the inner surface of the toilet bowl from the front to the rear, and the adhesion of dirt is suppressed.

In addition, the sanitary washing device of the present invention further includes a human body detection sensor that detects the entrance and exit of a user into and out of the toilet. The control part may be configured to rotate and distribute the bubbles on the inner surface of the toilet bowl by at least one reciprocating rotational motion when the human body detecting sensor detects that the user enters the toilet.

According to this configuration, in the case where the human body detecting sensor detects that the user enters the toilet, the rotating distribution of the foam is performed, that is, the cleaning foam is distributed on the inner surface of the toilet bowl by rotationally driving the direction of the discharge port of the distribution nozzle to at least one reciprocating motion. Thus, a foam film is reliably formed on the inner surface of the toilet bowl before use, and adhesion of dirt can be suppressed.

Further, the foam generating unit of the sanitary washing device of the present invention includes: a foam tank to which washing water is supplied through the water discharge amount variable unit by opening the on-off valve by the control unit; a lotion pump for supplying the lotion in the lotion tank to the foam tank; and an air pump which supplies air to the foam tank. The control unit may be configured to discharge the washing water or the washing foam in the foam tank from the spray nozzle.

According to this structure, it is possible to discharge the wash foam containing the detergent to the surface of the wash nozzle or the inner surface of the toilet bowl, instead of discharging only water or hot water. This can improve the cleaning effect and the effect of inhibiting the adhesion of dirt. Further, the cleaning foam containing the detergent can suppress the spread of odor. As a result, the user can be given a visually clean feeling and a comfortable feeling during use.

In addition, the control part of the sanitary washing device of the invention has a washing and commanding mode. In the wash and rinse mode, the control unit may be configured to open the on-off valve in a state where the wash pump for supplying the wash agent in the wash agent tank of the foam generation unit to the foam tank is stopped, to send the wash water to the foam tank through the water discharge amount variable unit, and to discharge the wash water from the spray nozzle.

According to this structure, the path from the foam tank to the distribution nozzle is washed with the washing water. This prevents the path and the distribution nozzle from being clogged due to the adhesion of the lotion and prevents the distribution nozzle from rotating poorly due to the adhesion of the lotion. In addition, the inner surface of the toilet bowl can be washed in advance, so that the adhesion of the washing agent and the like can be prevented.
